Abstract
The optimal design of a ridged waveguide is considered in this paper. The geometric shape of the waveguide is computed so that two prescribe d lowest modes of the transverse magnetic fields are obtained. A gener al formulation of the problem is presented: the electromagnetic proble m is solved by a finite-difference scheme, and the Ellipsoid and the T abu Search Algorithms are used to solve the optimization problem. This formulation should enable the design of guides to meet most practical specifications. Some computational results are given.
