ABSTRACT

The operator method is used to investigate frequency dependences of the absolute value of the reflection coefficient for a screen with coaxial-sector apertures in the cases of normal and oblique incidence of plane electromagnetic linearly-polarized TE- and TM-waves. The frequency-selective properties of the screen are compared with those of a screen with rectangular apertures.
