Plane wave scattering induced resonant modes of cubic resonator

Plane wave scattering from a cubic resonator is calculated by solving the combined field integral equation with the Rao-Wilton-Glisson basis functions and the moment method. High dielectric cube calculations show that magnetic and electric dipoles are found at the first and the second modes, respectively, whereas the third resonant mode has simultaneously strong electric and magnetic fields at the same resonant frequency. Furthermore, an analysis of a magnetodielectric cube is discussed.
