Abstract

Cylindrical electromagnetic bandgap structures excited by a dipole source are analyzed by a rigorous semi-analytical method using the T-matrix approach and reflection and transmission matrices of cylindrical harmonic wave expansions as the basis. Resonance and stopband characteristics in the transmission spectra of the cylindrical bandgap structures for the excited cylindrical harmonic waves are studied. The relationship between the transmission spectra of the cylindrical harmonic waves and the radiation patterns of the dipole source in both H-plane and E-plane is numerically investigated for three different configurations of cylindrical bandgap structures and different locations of the dipole source with respect to the cylindrical bandgap structures.
