Simulation Techniques

By using the numerical simulation techniques, the response characteristics of single split-ring resonator (SRR) in a broadband terahertz region are analyzed. We examine the transmission and dispersion characteristics of the SRR and show that there are different resonances while changing the orientations of electric field vector relative to the gap-bearing sides. Two significant resonances corresponding to electric response and magnetic response will be observed while the electric field vector perpendicular to the gap-bearing side, and only one electric resonance occurs when the electric field vector parallel to the same side. This will be a reference to design the possible terahertz metamaterials.

Photonic Crystal Ring Resonator

AbstractIn this paper, an ultra-fast all-optical modulator, based on a new shape of nonlinear photonic crystal ring resonator, is designed and studied. Numerical methods such as plane wave expansion (PWE) and finite-difference time domain (FDTD) are used to perform simulations. The modulation technique consists of carrier light controlling by means of input light signal and Kerr effect. The investigation of extinction ratio and insertion loss within the carrier input power shows that the choice of 0.7 W is the optimal value of that power to ensure the tradeoff between both characteristics. The suggested modulator demonstrates an excellent extinction ratio about 20.8018, a very low insertion loss of −13.98 and a short switching time about 13.4 ps. According to the obtained results, the modulator can be considered as an ultra-fast and ultra-compact optical component.

A ring resonator based on Silicon-on-Insulator (SOI) planar optical waveguide for micro biochemical sensor application is designed and simulated in this paper. The SOI optical waveguide is made with a ridge structure. According to the optical waveguide mode theory and the performance of the ring resonator, the size of the single mode ridge waveguide and the structure of the ring resonator are obtained. Based on the structure principle and the transmission mechanism of electric field of the ring resonator, the power transfer function and the parametric equation of sensitivity are derived. As a result, the value of Q of the ring resonator can reach 103 magnitudes. At last, the structure and the transmission mechanism of electric field in the ring resonator are simulated in MATLAB software.

Second-harmonic generation in split ring resonator multilayer nanostructure is studied with the finite-difference time-domain (FDTD) method. The fundamental frequency wave and the second-harmonic generation at the resonant absorption wavelength are highly localized in the dielectric layer, and the absorption peak is sensitive to dielectric constant of the dielectric layer. Under the excitation of the plasmon resonances mode, the strong local field induces an expected increase of the second-harmonic generation with conversion efficiencies 10−6-10−7. The distributions of fundamental frequency electric field and second-harmonic electric field inside the central dielectric layer region are also shown.

The article is devoted to the development of a two-resonator ultra-high-frequency (UHF) installation for defrosting and warming up animal colostrum, which ensures electromagnetic safety during continuous operation. As well as the development and study of the parameters of a microwave installation, which allows defrosting and uniformly warming up colostrum of animals in the field of a standing wave in the electromagnetic field of a traveling wave. A microwave installation is described with working chambers arranged in tiers in the form of an annular and conical resonators, containing, respectively, dielectric containers and dielectric conical plates. The out-of-limit waveguide is calculated and the radiation of the electric field through the loading hole is considered in the absence of the out-of-limit waveguide at a distance from the ring resonator that is greater than the wavelength. For uniform defrosting of colostrum in plastic bottles, they should be moved in a ring resonator and the magnetrons should be positioned with a shift of 120 degrees around the perimeter. Then the resulting strength of the electric field consisting of several initial fields will be equal to the vector sum of their strengths. To achieve a high heating rate of raw materials in the region of positive temperatures, it is necessary to provide a condition for heating a thin layer of liquid with the help of coaxially located conical dielectric trays
