MODAL AND RADIATION CHARACTERISTICS OF THE DIELECTRIC SPHERE EXCITED IN TM SYMMETRlC MODE

R CHATTERJEE, A K BHATTACHARYA

Abstract


The electromagnetic boundary value problem of the dielectric sphere excited in TM symmetric modes has been solved. Assuming that the fields on a truncated dielectric sphere excited by a coaxial line are the same as tho$e on a complete sphere, the radiation characteristics of such a structure have been derived. Calculated radiation patterns and gains of several structures of varying dimensions have been verified experimentally.
