摘要: Periodic guiding or radiating structures at microwave frequencies often possess symmetry properties in addition to their axial periodicity. These include rotation and reflection symmetries, either occurring alone conjunction with translations. symmetries influence the characteristics of electromagnetic fields associated structures. Therefore, useful information concerning can be obtained from without resorting detailed field solutions equivalent circuits. are conveniently analyzed by introducing operators for which structure is invariant. This paper shows that two operators, screw glide, particularly important determining dispersion Some implications these leaky wave antennas tube interaction circuits explored, consequences examined facilitate analysis synthesis periodic
