High Refractive Index Electromagnetic Devices in Printed Technology Based on Glide-Symmetric Periodic Structures

摘要: We demonstrate the beneficial effects of introducing glide symmetry in a two-dimensional periodic structure. Specifically, we investigate dielectric parallel plate waveguides periodically loaded with Jerusalem cross slots three configurations: conventional, mirror- and glide-symmetric. Out these configurations, it is demonstrated that glide-symmetric structure least dispersive has most isotropic response. Furthermore, provides highest effective refractive index, which enables realization broader range electromagnetic devices. To illustrate potential this unit cell, Maxwell fish-eye lens designed to operate at 5 GHz. The manufactured printed circuit board technology. Simulations measurements are good agreement measured peak transmission coefficient −0.5 dB achieved.
