Description: In this paper, a new family of Cassinian wave-guides
is proposed, simulating and calculation are finished with CST
Microwave Studio that based on Finite Integral Technique (FIT),
and some results are given. Electromagnetic field mode type of it
is TE, electromagnetic field is stronger near neck region, and
some resonance frequencies appear. The new Cassinian curve
wave-guides will possess higher power than ones of the
rectangular and elliptic wave-guides because the height at the
position where maximal electric field occurs is smaller.

Description: This gridlib collection has arisen decades of application programming
at NASA Ames Research Center involving (mostly) structured grids in 2- and
3-space, including many utilities for generating grid point distributions
along a line or curve. Of these, curvature-based and (extremely precise)
Vinokur-type distributions are most valuable. See program DISTRIBUTE for
driving such utilities. Transfinite interpolation, elliptic smoothing, and
grid perturbations are also supported here.-This gridlib collection has arisen decades of application programming
