V1 ECM

[Larry C Leung]

The tint (visible that is) that would have the least effect on Lidar
detection would be a shade of red. As far as radar signals, no visible
tinting (and most plastics in normal thicknesses would have much
detrimental effect on radar waves, which are long wavelenght and hard to
divert (they do not, however, have strong penetration, the high wattage
of microwave ovens (same general range of E+M waves) allows their
penetration of food and food containers. However, any form of metallic
materials between the reciever antenna will effectively act as a Faraday
cage, blocking the antenna from recieving the radar. Radar microwaves
cannot pass through a wire mesh of say window screening (notice the
opening size of the safety grid on the window of the old microwave oven,
no magic special glass here). Note, the reason light passes through
screening is that their wavelengths are MUCH smaller than the opening of
the holes in window screening. Films such as metallic tinting or the
"Insta-clear" windshields on some Ford/GM (I'm sure others) products have
openings WAY too small to pass microwaves, though adequate to allow some
light to pass through.
