Algorithm 934: Fortran 90 Subroutines to Compute Mathieu Functions for Complex Values of the Parameter
(Association for Computing Machinery (ACM), 2013-09)
Software to compute angular and radial Mathieu functions is provided in the case that the parameter q is a complex variable and the independent variable x is real. After an introduction on the notation and the definitions ...
Numerical analysis of penetration, radiation, and scattering for a 2D slotted semielliptical channel filled with isorefractive material
(Progress in Electromagnetic Research, 2005)
Electromagnetic penetration through an aperture into a cavity is considered. The structure of interest comprises a slotted infinite conducting plane backed by a semielliptical channel. Three independent integral equations ...
Currents on Conducting Surfaces of a Semielliptical-Channel-Backed Slotted Screen in an Isorefractive Environment
(Institute of Electrical and Electronics Engineers, 2005-07)
Electromagnetic penetration through an aperture into a cavity is considered. The structure of interest is a semielliptical channel flush mounted under a metal plane and slotted along the interfocal distance of its ...
Exact 2-D scattering from a slot in a ground plane backed by a semielliptical cavity and covered with a multilayer isorefractive diaphragm
(American Geophysical Union, 2008-12-13)
A semielliptical channel flush-mounted under a metal plane and slotted along the interfocal distance of its cross section is separated from the half-space above by a multilayer diaphragm. The cavity, the diaphragm, and ...
Acceleration of the Convergence of Series Containing Mathieu Functions Using Shanks Transformation
(Institute of Electrical and Electronics Engineers, 2003-04)
A modification of the standard application of Shanks transformation is shown to improve the convergence rate in certain cases where the straightforward application of Shanks transformation fails. Here, the straightforward ...
Algorithm 861: Fortran 90 Subroutines for Computing the Expansion Coefficients of Mathieu Functions Using Blanch’s Algorithm
A translation to Fortran 90 of Gertrude Blanch’s algorithm for computing the expansion coefficients of the series that represent Mathieu functions is presented. Its advantages are portability, higher precision, practicality ...
