Ha. Ragheb et al., RADIATION BY AXIAL SLOTS ON A DIELECTRIC-COATED NONCONFOCAL CONDUCTING ELLIPTIC CYLINDER, IEE proceedings. Microwaves, antennas and propagation, 143(2), 1996, pp. 124-130
The radiation properties of axial slots on a conducting elliptic cylin
der coated by a dielectric are investigated. The dielectric coating ha
s an elliptical outer trajectory which is not confocal with the conduc
ting slotted elliptic cylinder. A dual infinite-series solution based
on the boundary-value method is obtained with the aid of the addition
theorem of Mathieu functions. Both TM and TE cases are considered. The
dual infinite series involved in the solution are then truncated to g
enerate numerical results. The accuracy of the calculations is checked
by comparison with published data, Other interesting results for diff
erent geometries are then illustrated.
