A compact and broadband circular TE 01-mode oversized deformed waveguide bend for
high-power transmission line is proposed in this article. In order to obtain a circular TE 01 …

A tutorial exposition is given of cavity excitations and it is shown that relatively simple
analytical solutions for the excitation of acoustic fields in cavities with lossy walls can be …

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 …

In this paper, the acoustic scattering problem from a point source to a two-layer prolate
spheroid is solved by using the null-field boundary integral equation method (BIEM) in …

A systematic approach of using the null-field integral equation in conjunction with the
degenerate kernel and eigenfunction expansion is employed to solve three-dimensional …

This paper presents a new method in order to appreciate the roughness of elliptical or
spherical small bodies by using ultrasound. This thing is possible by knowing about 2–4 …

In this paper, we employ the null-field boundary integral equation method (BIEM) in
conjunction with degenerate kernels to solve eigenproblems of the prolate spheroidal …

In this work, we develop a full wave solution for the acoustic scattering by inhomogeneous
compressibility spheres having an impenetrable core. The solution is developed by …

Power series expansions for the angular spheroidal wave functions of the first kind Smn (c,
η), with small arguments c, are derived for general integer values of m and n. The various …
