- Electromagnetism encompasses much of modern technology. Its influence rests on our ability to deploy materials that can control the component electric and magnetic fields. A new class of materials has created some extraordinary possibilities such as a negative refractive index, and lenses whose resolution is limited only by the precision with which we can manufacture them. Using the new materials cloaks have been designed and built that hide objects within them, but remain completely invisible to external observers. The new materials, named metamaterials, have properties determined as much by their internal physical structure as by their chemical composition and the radical new properties to which they give access promise to transform our ability to control much of the electromagnetic spectrum.

Talk given at ISS2011: Light & Matter, the 36th Professor Harry Messel International Science School, held at the University of Sydney in July 2011.
recommend playing at 1.5x speed & the first 20 minutes is history so to start immediately at the actual lecture on metamaterials fast forward to/start playing at 20 ~ 21 minutes into the video.
Thank you! God bless!! 🙏🏾✝️❤️
10:36 "....light is a dance is between electric and magnetic fields ....". Beautifully said, I'll remember that sentence from now on. 🙏
35:10 "how the hell can you build it?" LOVE that response!
This is absolutely spot on.
Excellent summary
Wow yes
Audio is painful
would the man in the cloche also see behind him?
Mr Pendry I believe you are the person i need to speak with regarding to this very large metallic meteorite its a super niva its meta material. I had it tested and it passes all hime tests im T the stage of getting it classified so i can sell it please i can donate some of this to you. All i am asking for is to get cone ted with a private buyer and to get it classified. Please contact me as soon as possible thank you.

YES! BUT DID THEY REALLY GET TO THE MOON AND BACK? (HAHAH!)
rubbish
come on,,, something, cannot go through nothing. i am so glad Einstein non seance is finally going out the window. the plasma around the sun bent the light, lots of things bend light, light travels through aether at a given rate, but that does not limited other materials exuding that speed.
We now have patent pending status on Quantum Stealth (Invisibility Cloak) and released videos demonstrating the capabilities th-cam.com/channels/iPMHslCqorDy5ETsg6MhFw.html
