WebThe field solutions of a cylindrical cavity of length and radius follow from the solutions of a cylindrical waveguide with additional electric boundary conditions at the position of the … WebThe solution of Maxwell’s equations for a piecewise homogeneous medium of cylindrical symmetry has been obtained. The parameters of the cylindrical waveguide modes have been calculated on its basis. The conclusions are confirmed by numerical calculation of the first four modes of a hollow metal waveguide operating as a mode convector.
WebTransformation optics theory [25] proves that the TE-polarized electric modes of the cylindrical MFE are transformed into radial-polarized modes in the SGW, so both have the same imaging properties. When the waveguide thickness is small enough, the variation in the refractive index within the two spherical shells can be ignored, resulting in a ...
