Direct and inverse dipole electromagnetic scattering by a piecewise homogeneous sphere
TL;DR: In this paper, the authors investigated the direct and inverse electromagnetic scattering problem by a piecewise homogeneous sphere, excited by an interior or exterior dipole, and used the low-frequency assumption to derive asymptotic far-field expansions of the Green's function.

An Annular Waveguide Slot Antenna
Siamak Ebadi,Keyvan Forooraghi +1 more
TL;DR: In this paper, a novel annular slot cut on the broad wall of an annular waveguide is presented and an equivalent circuit model is suggested for the structure based on its similarity to the rectangular slotted-waveguide case.
