In this paper, Hexagonal Split Ring Resonator (HSRR) and Square Split Ring Resonator (SSRR) are designed using HFSS simulation software. Both split ring resonators are based on the Metamaterial and same parameters. Then after compare the simulation result of HSRR and SSRR. HFSS simulation of the Hexagonal SRR shows improved Return Loss and VSWR i.e. -44.7 dB and 1 respectively compare to Square...

We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring reso...

Previous second-harmonic-generation experiments on metallic split-ring-resonator arrays have been performed at fixed fundamental laser center frequency. Here, we perform nonlinear optical spectroscopy on a first set of samples, revealing pronounced resonances. Furthermore, to clarify the role of higher-order split-ring resonances, we perform additional experiments on a second set of samples in ...

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...

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...

The properties of artificial isotropic microwave composites which would possess simultaneously negative permittivity and permeability are studied theoretically. Four kinds of composites are considered. Two of them concern media with split-ring resonator particles with different particle arrangements. The other two are realized with Omega particles. An analytical antenna model of the electromagn...

In this paper, an artificial neural network model is proposed to find out the resonant frequency of a metamaterial based Hexagonal Split Ring Resonator (SRR). The main advantage of Hexagonal SRR is small electrical size at resonance (electrically small) in the microwave regime. The method can be used for a wide range of different depending parameters (effective radius of the Hexagonal ring, spl...

In this present work, we propose and demonstrate a resonant structure that solves two major problems related to the split-ring resonator structure. One of the problems related to the split-ring resonator structure is the bianisotropy, and the other problem is the electric coupling to the magnetic resonance of the split-ring resonator structure. These two problems introduce difficulties in obtai...
