Scattering of an obliquely incident E− polarised plane wave from ensembles of slotted cylindrical cavities: A rigorous approach

Abstract

Abstract A rigorous theory is developed for the multiple scattering analysis of an E− polarised plane wave from an ensemble of 2‐D slotted arbitrary cylinders. The Method of Analytical Regularisation, previously applied to the solution of scattering wave problems for isolated slotted cylinders, is generalised to problems incorporating ensembles of closed or slotted cylinders. Numerical calculations of the complex eigenvalues, Q− factors and resonant current densities are performed for various configurations of two slotted circular or elliptical cavities, focussing on an accurate assessment of differing peculiarities of the mutual resonant electromagnetic coupling.
