N. Courivaud et al., A RIGOROUS DESIGN OF MILLIMETER-WAVE-GUIDE DEVICES USING THE 3D FINITE-ELEMENT METHOD, International journal of microwave and millimeter-wave computer-aided engineering, 4(4), 1994, pp. 327-335
A rigorous filter design using the finite element method and an optimi
zation process is described. To show the validity of this method, it i
s here applied to a millimeter-wavelength metal insert filter. The inf
luence of higher order mode interactions and of metallic losses is als
o described. (C) 1994 John Wiley and Sons, Inc.
