Abstract
The frequency-angular characteristics of the reflection of TM-polarized waves from thin (thickness up to 1/200 wavelength) artificial magnetic conductor (AMC) and radio absorber (RA) based on band-reflecting and band-passing gratings are presented. It is shown that the operating frequency bands of the AMC and RA expand tens of times when the angle of incidence changes from 0 to 89 degrees. In this case, the value of the ratio (is the difference in wavelengths at the edges of the absorption band and is the thickness of the RA) increases to 30.
