A novel analysis to compute the admittance characteristics of the slots cut in ( ) the narrow wall of a rectangular waveguide also called edge slot is presented. The slot aperture field is expanded in terms of entire domain sinusoidal basis functions and is solved using Galerkin's method. The comput

β¦ Synopsis
There is no steep rise, and there is a tendency toward saturation when V is nearly equal to 2.5. We thus find that a reduction of the frequency from the optical to the microwave region results in a separation of the mode near cutoff. Moreover, in the optical region, the modes are more size sensitive for smaller sizes than for larger sizes. This is not the case for a microwave guide, where the size sensitivity remains more or less unaltered in the entire range of V-values.

A new set of edge-conditioned basis functions is used to determine the modal characteristics of a large variety of nonstandard waveguide structures. Since the electromagnetic field includes the proper edge conditions at metallic corners and since the new basis functions are readily Fourier transform
A general approach to impose homogeneous boundary conditions on algebraic systems deriving from variational formulations of di!erential problems is presented. The proposed approach proves to be e!ective and its performances are particularly enhanced when sparse matrices are dealt with. It applies to

Collocation methods for applying essential boundary conditions are deΓΏned as those methods in which conditions are enforced exactly at a discrete set of boundary nodes. In mesh-free methods, this is usually accomplished by replacing rows of the matrix equations which result from discretization of th
