In this paper, both simulations and measurements are used to explore the propagation properties of ultrahigh-frequency (UHF) waves traveling through building structures and, in particular, windows. The propagation influence of several features of a t

The paper introduces a new way for the termination of periodic waveguides using integral equation like simulation techniques. Exploiting the complex coordinate interpretation of a perfectly matched layer (PML), we can terminate a periodic waveguide b

In this paper, we analyze the scattering at discontinuities in cylindrical waveguides, starting from a vectorial eigenmode expansion and by introducing perfectly matched layer (PML) boundary conditions. The structure under study is enclosed in a meta

A class of nonreciprocal bianisotropic media, known to allow a decomposition of electromagnetic fields into two individual parts with certain restrictions on polarization defined in terms of two arbitrary vectors, is studied. The field decomposition

In this paper we will study the Green dyadics and the factorization of the Helmholtz determinant operator for a new class of homogeneous bianisotropic media. That new class of media is derived from previously studied media using a rotational duality

The class of self-dual linear bi-anisotropic media can be defined in three different ways. It consists of media which are invariant in a duality transformation, allow factorization of the second-order dyadic Helmholtz operator in terms of two first-o

Conditions for the most general bi-anisotropic media in which the electromagnetic field can be decomposed in two components with respect to two six-vectors were recently derived by these authors. In the present paper it is shown that the fourth-order

Large-size electromagnetic absorbers are mainly used in anechoic and semi-anechoic chambers for electromagnetic compatibility testing. Therefore, the determination of the reflectivities in the low-frequency range (30-300 MHz) are of paramount importa

It is shown that there is an optimal finite linear combination of B-splines (denominated modified B-splines) such that a pertinent low frequency condition called M-flatness is satisfied. A profound relationship of the modified B-splines with the beta
