Abstract :
The method of moments (MM) and geometrical optics (GO) can be formally combined into a hybrid MM-GO technique. Wire-type antennas are treated by the method of moments, and their interaction with a large curved surface is accounted for through geometrical optics. Thus, in this communication, geometrical optics is used to account for the interaction of a monopole antenna with the curved surface on which it is mounted. Two hybrid MM-GO technique formulations for doing this are discussed. Results are shown for the impedance of a monopole on a circular cylinder as the radius of the cylinder is varied. Some of these results are compared with experimental measurements and good agreement is shown between the calculated and measured results.
