Can a fire alarm in my apartment hurt or damage my cats ears? All three of them went off tonight due to burning food in the oven (opps!) Since then, my cat has been hiding and acting terrified! He even tried to run outside (which he never does) it was like he was trying to run away! :( He wouldn't even come for his favorite food! What is wrong with him? This happened over an hour ago, and he is still freaking out..
Reflective? Any grounded metal should reflect an EM wave (aluminum foil, copper, etc.).
Get the surface mount type and use a stud finder to know where to mount them. They're not heavy and a drywall anchor would work, but I like to mount stuff into solid wood whenever I can. Be sure to change the batteries twice a year.
The stealth is made from several materials. And its angles reflect the radar in other directions. But as said above carbon composites or carbon fiber is very strong light weight. Also if you know of any one in the military see if they can get you some olive green paint. The paint will absorb 15% of the radar and disperse the other 85% in all other directions Instead of the direction the radar is coming from.
In WWII they used tin foil chaff. It's just tin foil strips.
