superstrong handyphone glass with invisible osmium wires

Tablet PC glass as well as handyphone glass is better with greater strength Using invisibility approaches like flow around gradient refractive ndex or negative index material or negative refractive index materials this technology just curves light around a microfine mesh of hyperstrong metal like osmium

TabletPC glass as well as handyphone glass is better with greater strength

New approaches to invisibility from curving light around an object have been appearing quite frequently.

Using invisibility approaches like flow around gradient refractive index material or negative index refractive materials like microcolumn arrays this technology just curves light around a microfine mesh of hyperstrong material like osmium metal or possibly a carbon polymer.

super tech kudos if they place the mesh between the active elements at the display matrix so it tends to be invisible anyway.

This is a Public domain idea from a few hours ago.

       another approach to superstrengthening tempered glass could be using doped Si at glass to make it conductive to induced electromagnetic fields   

       Then induce a giant magnetic field, like the kind at electromagnetic coin squishers (link) while the glass cools to create orders of magnitude stronger tempered glass.   

       Further you could shape the microareas of conductive silicon differently (antenna patternization) so they absorbed different RF frequencies, thus adjusting the amount of EM coin squish energy to be different at different areas of the glass, so the sides could be hyperstrong along certain lines with the major surface strong at particular ways

       Isn't osmium dangerous?

       Dunno, but it is REALLY heavy; probably ot the best material to use in any great quantity in a hand-held device.

       I want to understand this so badly... and in a way, I guess I do.   

       Its compounds are toxic, but the pure metal is quite inert. I don't know if it's hyperstrong, though. It's very hard, but that's not the same thing.

       The issue being that "invisibility" metamaterials only work in a very narrow frequency range, and (AFAIK) none have been designed that can work in frequencies high enough to see; they're more radio or occasionally IR. In fact, it's pretty much impossible to route something as broad-spectrum as visible light around anything.   

       Also, they tend to be fairly bulky. The glass will likely be significantly larger than the smartphone itself.

       I'd prefer putting your magical invisibility material around the entire phone, so I could talk on the phone without people noticing. Don't mind me, my (apparent) rant to no one, or this weird blur by my right ear.
