Thin Broadband coating

Тонкие широкополосные покрытия
Thin broadband coatings, which effectively absorb electromagnetic waves in a wide range of frequencies, are based on amorphous ferrimagnetic microwire (see the picture). The research resulted in creating a know-how to study FMM in which waveguard with a displaceable piston replaced traditional resonator. Signal intensity measuring in fluctuating external magnetic field was done with a traveling detector. It became possible to calculate standing-wave ratio and phase shift. The research was done in collaboration with CKBRM and IPMT RAS.
