The azimuth distribution (\(0^{\circ }<\phi _{o}<360^{\circ }\)) of the phase and normalized magnitude of the scattered electric field from two dipoles for (a) oblique incidence (c) normal incidence. The azimuth distribution (\(0^{\circ }<\phi _{o}<360^{\circ }\)) of the phase and normalized magnitude of the scattered electric field from rectangular loop for (d) oblique incidence (f) normal incidence. Symmetrical and non-depolarizing scattering structure (b) without radial resonance [two equal-length coupled dipoles] (e) with radial resonance [rectangular loop]. All the data are obtained in simulation.
