- Abstract
- A structure of a radio absorber (RA) with a high stability of resonance frequency based on a resistive film with a sheet resistance of 120 Ω/sq and an artificial magnetic conductor in a pair of capacitive gratings on a dielectric layer with a high permittivity (epsilon_1 >>1) metallized on the opposite side is proposed. The results of numerical calculations of the frequency–angular dependences of the RA reflection coefficient confirm preliminary estimates obtained from analytical expressions. For example, at epsilon_1 = 20 , the shift of the resonance frequency is no greater than 2% at angles of incidence of phi=0^o...60^o , and the bandwidth-to-thickness ratio is 4.29 at phi=0.
