Resonant Frequencies of Split Ring Resonator in Respect of Angle between Slits
نویسندگان
چکیده
In this paper we proposed the method for calculation of resonant frequencies of split-ring resonators (SRRs) as a function of the angle between slits. Method is based on transmission line (TL) approach and can be used for calculation of resonant frequencies of broadside and edge-coupled, as well as of multiple SRRs. Resonant frequencies are also calculated using 3D EM simulations based on method of moments and compared with our model. It is shown that very good agreement is achieved in case when substrate thickness is smaller. Limitations of the model are discussed.

Add-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators
Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....
متن کاملDesign of Wide-Band Metamaterials Based on the Split Ring Resonator Model
It is shown that the highly resonant characteristic of split ring resonator (SRR) can be significantly improved by introducing new pole pairs to Lorentz atomic model, and by adjusting their resonant frequencies and damping terms. A new SRR cell of metamaterials containing all these required poles is then designed for the desired bandwidth.

متن کاملSaturation of the magnetic response of split-ring resonators at optical frequencies.
We investigate numerically the limits of the resonant magnetic response with a negative effective permeability mu(eff) for single-ring multicut split-ring resonator (SRR) designs up to optical frequencies. We find the breakdown of linear scaling due to the free electron kinetic energy for frequencies above approximately 100 THz. Above the linear scaling regime, the resonance frequency saturates...
متن کاملCalculation of Resonant Frequency of Hexagonal Split Ring Resonator Using Ann
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...
