Mode-converting metasurfaces are passive, lossless devices that can be designed to transform a set of incident modes to a desired set of transmitted modes. In this paper, mode-converting metasurfaces are utilized to synthesize arbitrary, azimuthally-

Modal network theory has proven to be a useful tool in analyzing waveguide discontinuities. Ports of a modal network correspond to waveguide eigenmodes on either side of the discontinuity. In this work, modal network theory is extended beyond convent

This article investigates wireless power transfer in the Fresnel zone using cylindrical vector beams. First, a generalized coupling coefficient between two circular apertures in the Fresnel zone is derived. From the generalized coupling coefficient,

A general method to convert between azimuthally-invariant TM 0n cylindrical waveguide modes using metasurfaces is presented. Mode conversion is achieved by a metasurface comprising cascaded electric impedance sheets that vary radially. The metasurfac

A general method for designing metasurface antennas with radially-polarized, azimuthally invariant aperture fields is introduced. The antennas consist of a metasurface (a cascade of inhomogeneous electric sheets) above a coaxially-fed, cylindrical ca

In this work, we apply the Discrete Hankel Transform (DHT) to solve electromagnetic problems that involve cylindrical waveguide structures. We demonstrate the DHT's use by applying it to the simple problem of radiation from an open-ended waveguide. T
