This paper describes a simple analysis of the guided waves in an eccentric circular
waveguide based on the bipolar coordinate system (BCS). The separation of the variable …

In this study, a design, simulation, fabrication, and measurement of the TEM‐TE11 mode
converter antenna (MCA) like a pelican beak are investigated. The working frequency of the …

The hollow waveguides with angular deformation are widely used in high power millimeter
wave system. In this manuscript, the cutoff wave number of the quad-polar waveguide with a …

A design method of oversized multimode waveguide filter, which can deteriorate the
unwanted modes without affecting the operating mode, is proposed to restrain the trapped …

A configuration of multistrip lines mounted on a multilayer dielectric-coated elliptic cylinder is
investigated in this paper. A full-wave analysis and a moment-method calculation are …

In this paper, a pattern director antenna (PDA) with 4 GHz bandwidth was designed,
simulated, and measured. In the past, to convert a donut-shaped pattern into a directive …

This Letter presents the closed‐form expressions of the unloaded Q‐factor in metallic
cavities with equilateral triangular cross section, computed from its analytical resonant mode …

This paper addresses the robust mode computation of the metallic hollow cylindrical
waveguide with parabolic contour. Although this waveguide can be solved by separation of …
