Full-vector Body-of-revolution Modeling with Two-dimensional Cartesian-grid-based Algorithms
Equivalent permittivity and permeability profiles are proposed to represent threedimensional body of revolution (BOR), or a segment of it, by its axial half cross-section while retaining Cartesian-like formulation of Maxwell equations. Alongside the usual separation of variables permitted by BOR geometry, this paves the way for rigorous finite-difference modeling of axially symmetric resonators and homogeneously bent waveguides with use of existing twodimensional, Cartesian-grid-based codes by means of mere redefinition of material permittivity and permeability. The method is validated by finite-difference frequency-domain (FDFD) modeling of air-filled circular cylinder with PEC walls, and shielded anisotropic dieffectric resonator.
