Abstract

In this work, studies and comparisons have been carried out on the performances presented by numerical codes for the analysis and design of compact, light-weight, and high-performance microwave guided-wave devices that employ dielectric components. The features of original numerical codes based on boundary elements (BEM) have been compared with versatile canonical codes, such as those using finite elements (FEM). The BEM implementations have expressly been conceived for the study of a variety of electromagnetic problems in dielectric structures, and show notable advantageous properties as concerns accuracy and efficiency. The relevant basic formulation is oriented to the modal analysis of arbitrary dielectric waveguides, but it can be applie
