"Smart" windows (electrochromic glass) - The optic electronics device is:

electrochromic glass ("smart" glass), which changes from light to dark (clear to opaque) and back again, at the push of a button

Flexible window-type black electrochromic device (how much invisble is the suitcase?)

WITCH IS BASICLY THIS...HOWEVER STILL WITH OPTIC-ELECTRONICS..RADIANT BARRIER

http://www.radiantbarrier.com/plus-insulation.htm

welcome back to war! Good morning! so, again how to cover a yellow cake from the gamma rays radar detection? I've been here making a quick search, and something come up, why not a quartz crystal modulator??? and how exacly can be used,,, can we skip the vaccum??? we already checked that vaccum deposit would work...but there's some difficulty on the right transportation for that! In this case we need to microbalance the gamma ray frequency...

20 YELLOW CAKES READY TO USE...

I ended the computation discipline for a while, I achieved my goal, I let you think about it! So, you're saying you have 20 yellow cakes ready to use? And you say the botton question are in fact the gamma rays detection; I know that! I've been trought a lot of aspects, including the temperature, nevertheless gamma emissions cross trought cold; I've been trough dense materials, and I defintely not overcome the lead question, because its only possible to cover the nuke with as much dense lead is, or to replace it, platinium, the most rare and expensive metal that is; So, don't break our agreement, and I will find a solution.

 Ok! I have a break here !!!! electronics !!! let me start by this
"If the metal is not grounded or connected to any other electron source, there will be excess positive charge accumulated on the surface which will stop further photoemission"

 in that case we need an eletrostatic material...as a conductor to change the charge
