Abstract :
Cylindrical guided structures, such as coaxial lines or circular waveguides, have been widely adopted in microwave engineering, while study of electromagnetic band-gap (EBG) structures has become an interesting topic in the area. In this research, some studies are conducted through the EBG implemented on cylindrical guided structures, using a body-of- revolution finite difference time domain (BOR-FDTD) method. It is a two-dimensional (2-D) algorithm, applicable to analysis of cylindrical structures thanks to their axial symmetric properties. A periodic series of dielectric slabs are placed longitudinally along the guided structures for EBG formation. Clear band-gap properties are observed through the spectra of the scattering parameters. BOR-FDTD offers an alternative solution for such structures than a full 3D-FDTD analysis, as the former approach provides more efficient savings in terms of computational time and memory allocation.
