We propose a short period undulator based on the electromagnetic field pattern in THz-driven split ring resonator structure. An analytical model is developed that allows us to assess key performance parameters of and estimate emitted radiation spectrum. Different geometric configurations are compared detail using numerical simulations. A 100 MeV electron bunch with 5 pC charge shown emit narrow...

Abstract Ring resonator is an essential element in silicon integrated circuit, it widely used as filter, wavelength multiplexer and switch single-mode operation regime. As the rapid development of mode division multiplexing (MDM) technique, ring that can process multi-mode signals simultaneously uniformly highly desired. However, severe modal dispersion makes identical transmission for differen...

This paper discusses the design of a high gain right-hand circularly polarized millimeter-wave frequency reconfigurable antenna array. The 16-element array is designed to reconfigure its operating over both K- and Ka-bands. More specifically, reconfigurability ensured through integration modified ring resonator along with array's sequentially rotated stacked feeding network. four distinct bands...

Development of Analog Nonlinear Materials Using Varactor Loaded Split-ring Resonator Metamaterials

In this paper, Using a 2D photonic crystal and a novel square ring resonator,several compact and simple structures have been introduced in the present paper toconstruct optical add/drop filters and multi-channel filter. The difference structures hasbeen designed and simulated by using the proposed square ring resonator and differentdropping waveguides. To do analyses, th...
