Other University Research on Invisibility

by Guy Cramer. President/CEO of Hyperstealth Biotechnology Corp. and inventor of Quantum Stealth (Light Bending Material)

The Professor behind the first Invisibility Cloak was knighted by the Queen for this work in 2012

Professor Sir John Pendry (theoretical physicist) is the leading theorist in optical materials in the world today who is currently working at the Imperial College in London. In 2000, Sir John published a series of papers building on forgotten work by Russian physicist Victor Veselago from 1968, which laid the theoretical ground for the development of special left-handed or metamaterials that could be used to form perfect lenses.
In 2008 he developed invisibility cloak layout of a copper cylinder (shown below) that was able to bend microwaves around an object which proved that these waves could be bent. Visual invisibility was not achieved but this experiment demonstrated that bending light (which is just a different frequency from microwaves) was a probability and not an impossibility.  
Professor Sir John Pendry has been working with college and university teams on creating lenses which have demonstrated cloaking in very small objects such as a few microns to a material of 10 centimeters across which could bend light behind it, demonstrating proof of concept. See his Ted Talk presentation below.

Professor Sir John Pendry was contacted by David Hambling to review our Hyperstealth videos and comment for an article for New Scientist, he described it to David as " an ingenious application of classical optics". David shared this with me but did not include it in the article. What he did include from the Professor " This is a limited, but useful, form of invisibility,". (3)

Engineering professor Andrea Alú explains metamaterials and their ability to bend electromagnetic waves and potentially light waves one day based off the 1968 theoretical work of Russian physicist Victor Veselag.

In the video above he points out that Victor Veselag theorized that if this theoretical material existed, it would bend light but items would be in mirror reverse and that is exactly what happens with our patent pending Version-2 material in the video below . 

Our modified lenticular material is not a hoax but the fact that every time a green screen video was released claiming this group or person had created an invisibility material, I would be bombarded with texts and Emails by friends, shareholders who had never seen our material and even advisors who had seen our actual product at military demonstrations I had done, believing that someone had either stolen our idea or had stumbled onto something equal or better.

Lenticular lens material has been available for decades (it was developed in the late 1920's) and our cloaks could have been easily developed by someone prior to World War II, imagine the significance if one or both sides had this during the war. The outcome would likely be much different.

Why wasn’t this discovered long ago. Most Physicists thought it was impossible and as such there was no real research effort into finding a solution, no funding could be or would be granted to this "science fiction". When I demonstrated to the Chief Scientist at PEO Soldier (Program Executive Office) of the U.S. Army and he determined I was actually bending light, he told me they could not provide funding as invisibility was thought to be impossible so we don’t have a requirement to make an object invisible.  

I can tell you that people seeing it in person usually have a stunned look when their brain tries to determine what is happening, why can they see the table but not the big object on it?

I solved this mirror image problem with Version-3 a few years later as demonstrated in the video below.

Quantum Stealth is still in prototype stage, the manufactured product should look extremely clear with less distortion and less refletion with anti reflective coatings in comparison to the prototypes shown throughout the videos. For those that claim they can "see the lens" or "see the blur where the target is" need to take that into account. I also need to point out that in real world combat, engagement distances are typically 40 to 50 yards and not within 10 feet of the lens like every one of my videos demonstrate. This won't be a blurry rectangle on the battlefield, it will be "nothing" of the sort!  

Are we the first to accomplish true invisibility? The first to theorize that bending light to make something invisible was this was Russian physicist Victor Veselag in 1967. The first to demonstrate that you could bend a wave to make something invisible, albeit in the microwave spectrum was Professor Sir John Pendry in 2008. In 2010 I discovered that the lenticular lens could bend light and was able to demonstrate such to the military in 2011. The resulting years brought about numerous Versions which both confirmed Victor Veselag's theoretical properties and Professor Sir John Pendry's expectations that bending the microwave spectrum would lead to the visible spectrum one day. Their team had recently shown that it could be done with a 10-centimeter piece of natural calcite crystal which is now known as the Birmingham Calcite Cloak, but this is a thick material which would be cumbersome and expensive to scale up to real world applications. 

If someone asked who was the first to make a practical invisibility cloak that functioned in the visible spectrum then the answer would be Guy Cramer and we could include broadband invisibility cloak into that description.   


People have also questioned my use of the term "Quantum" as a hyped reference that Quantum Mechanics is behind the optical properties. This video below is Part 2 of 3 from our patent pending "Laser Scattering, Deviation and Manipulation" and does provide compelling evidence that Quantum Mechanics is at play, scientists have since confirmed that's what is happening. All 40 claims of our laser patent application have been approved by the WIPO and that decision will be posted on their site in the next few weeks. 

Now that we’ve released over 100 minutes of video confirmation of our patent pending light bending material (Invisibility Cloak) we call Quantum Stealth, which are all available to watch at  www.hyperstealth.com. I want to review the key component that most people and reporters are missing.

Version-1 of our material is a raw lenticular lens with parallel lenses placed in the same orientation as a target to hide. The material has been available since the late 1920's and is not patentable. There may be a few applications of this Version-1 which are patentable but the real discovery here is not Version-1 but Versions-2 and up. By placing two lenticular lenses back to back, I inadvertently invented a material that has a Negative Refractive Index which had been theorized by a Russian physicist in the late 1960’s and he determined that discovery should lead to invisibility, but with everything reversed in the background. This is exactly what happens with our Versions-2 material as shown in the picture at the top where I'm walking to the right but my body and legs in the material are moving to the left.  This orientaion problem is corrected with Version-3, which will be shown later.

Before we get into my discovery let's look at the journey of this ray optical metamaterial to find out why it has this unique set of properties

Invisibility Invented

The Discovery of a Material with a Negative Refractive Index leads to Invisibility.

To create a thin material which functions as a "negative refractive index" as seen in the photo at the top, two pieces of lenticular lens sheets are placed back to back with water or oil to bond them and aligned in parallel. To create the same but with a concealed section in the middle, the lense sheets need to be offset and not parallel, this is only a difference of a few millimeters.
