    This is absolutely correct Prof.

    it almost looks like it looks forward in time, but maybe its like a an inductor rather than capacitor?

    For example a full Medical Extended Reality Invisible Headset, including communication and eye lens.

    An audio presentation with highly variable amplitude, is like watching a movie with the lights in the room turning off and on. Get a negative refractive index on your audio Mr. Smartypants!

    I have a full invisible Holographical Optical Element System incl, ultrasound hearing, subvocalisation silent speech, invisible luneburg superlens for Virtual Reality with over 40 tools for augmented reality.

    I see no need for electromagnetic as natural light will supply the exact light required. If you take fiber optic material and with precise placement from the front to the rear, the light should in theory flow both ways. A very machined (tight) this proper optic material knit cloth with this precision placement would pass light around the subject being wrapped in the material, and light is forced to bend around. Light and dark are all that is important for the first phase as our eyes will do the rest of the hiding. I understand I am not explaining well, but I have the full image in my head... a 3 dimensional view. Light that may be dimmed could be sorted out with nano materials carrying the light further if needed. The problem will always be, as long as the subject is still, should be "ALMOST" invisible. The way the endings of this nano fiber is cut, could prism to a degree, but in this case, simplicity might serve this technology much better.

      I see this comment, and I think I get what you're getting at. I think the main problem with this is that to create a mesh like this, you would need a entry and a exit point on opposite ends, and you would need one for every point on the object(lets say a sphere). This would mean naturally that the center's mesh gets exponential more dense the more points of passage you place on the opposite surfaces. This would mean that this structure would be impossible to use practically, and possibly even at all.
