Sk. Popalghat et Pb. Patil, STUDY OF RECTANGULAR WAVE-GUIDES WITH GROOVES OF IRREGULAR SHAPE USING THE FINITE-ELEMENT METHOD, Sadhana, 23, 1998, pp. 269-280
Electromagnetic wave propagation through grooved waveguides is studied
using the finite element method (FEM). The effect of grooves of irreg
ular shape on TE10, TE20 mode frequencies and passband is studied. The
variation in cutoff frequencies for TE10, TE20 mode and passband is o
bserved.
