The transfer matrix approach is applied for analysis of waveguides loaded with a uniaxial pseudochiral Ω slab. In particular a pseudochiral parallel plate and rectangular guides are investigated. Based on the numerical analysis the influence of the pseudochirality on propagation characteristics and field distribution are examined. Other feature such as a field displacement phenomenon appearing in the both considered structures...

The thesis concentrates on comprehensive theoretical, numerical and experimental analysis of guided wave propagation in bars embedded in concrete or mortar. The investigations are focused on a particular type of objects representing a laboratory model of a ground anchor. Complex description of wave propagation phenomena in partially embedded bars is given and its application in...

This paper introduces a novel technique for enhancing the efficiency of the finite element method (FEM) by incorporating special modules, called macromodels, into the standard eigenvalue formulation. The number of unknowns in the separated macromodel subdomain can be significantly reduced by orthogonal projection, using the efficient nodal order reduction algorithm. The idea of macromodels implementation is demonstrated on a simple...

Wykorzystując metodę dopasowania rodzajów opisano metodykę połączenia zastępczego pola rozproszonego od dowolnej konfiguracji prętów dielektrycznych lub wykonanych z metamateriału z pobudzeniem z falowodu prostokątnego. Zaprezentowano częstotliwościowe charakterystyki macierzy rozproszenia dla rodzaju podstawowego. Zaobserwowano filtrujące własności badanych układów.
