The complex-source (CS) method in conjunction with the spherical-multipole analysis is used to explore and demonstrate the different local phenomena associated with beam-wave scattering by acoustically hard or soft circular cones. The illumination by

Starting from the question how the mutual cancellation of opposite-phase plane waves is compatible with the conservation of energy, the energy flow of interfering electromagnetic waves is investigated. Furthermore, it is shown how a multipole expansi

The internally stored electric energy (Q-energy) of a disk monopole antenna increases as compared to a monopole antenna without a top disk. Recently it was shown that the Q-energy can be significantly reduced and the bandwidth increased by shielding

A plane-polar multipole approach has been used to rigorously solve the scattering and diffraction of a TM-polarized uniform complex-source beam (UCSB) by a perfectly conducting finite wedge. The numerical results include a comparison between the scat

This paper compares two radar configurations operating in the W-band with different antenna systems for measuring particle streams in the near-field range. A complex source beam is employed to describe the field characteristics. This new approach is

A new analytical expression of the normalization constant for the associated Legendre functions of the first kind of arbitrary degree and order is presented. The evaluation of such normalization constants is needed, for instance, if the scalar or ele

A Uniform Geometrical Theory of Diffraction (UTD) solution for inhomogeneous plane wave diffraction by a Perfect Electrically Conducting (PEC) wedge has been presented in [1]. More recently, this solution has been extended to analyze the case of an i

The paper addresses the combination of the spherical-multipole analysis in sphero-conal coordinates with a uniform complex-source beam (CSB) in order to analyze the scattering of a localized electromagnetic plane wave by any desired part of a perfect
