    it’s called dielectric mirror, this type of mirror can be made to be extremely effective over narrow range of wavelengths and it’s used in lasers for this reason. this is also the only way to manipulate extreme UV (13nm tin source, used in EUV semiconductor manufacturing)

    similar effect is responsible for blue color of some butterflies and feathers that don’t contain blue pigment

    i understand that these are mass manufactured 7" drones made from standard components. commercial cloverleaf antenna, motors + blades, frames are sometimes bought and sometimes 3d-printed. battery pack, electronics, and of course payload are custom. there are also drones that use completely nonstandard bands for control and video, this is useful against jammers and if you’re printing your own boards, changing bands to something weird takes zero effort
