Plane electromagnetic wave diffraction on an unclosed cone structure

Abstract

The problem of plane electromagnetic field wave on a cone with periodical slots cut along rulings is considered. The plane wave propagates along the cone axis. It is shown, that electromagnetic problem is equivalent to the solution of the linear algebraic equations system for Fourier coefficients of scattered field components. The numerical algorithm for solving this system is constructed. Coefficients dependence on the conical structure parameters is studied. Slot dimension effect on scattered patterns is investigated for the cone with one slot.
