A chiral coding metamirror constructed with optically transparent material is proposed here to generate vortex beams carrying different topological charges in different directions. Dispersionless phase diagram covering 360 degrees is achieved based on the theory of Pancharatnam-Berry phase. The proposed metamirror unit has circular dichroism (CD) with near-perfect spin-selective absorption across a wideband and is insensitive to incident angle. Multi vortex beams can thus be selectively generated at the designated frequency, which avoid information interference.

Photonic crystal has a variety of applications, e.g., can be used to design photonic crystal fibers, cavity optomechanics, photonic crystal antennas, etc. Most of the raw materials for the photonic crystal are Si, SiN, GaAs, etc., and lithium niobate is a new type of photonic crystal material, because of its rich photoelectric effect, stable physical and chemical properties, and wide light transmission range. With the continuous development of lithium niobate single crystal thin film processing technology, it is now possible to provide single crystal thin film lithium niobate with a thickness of 300-900nm, making it possible to use lithium niobate for photonic crystal fabrications. Therefore, this paper investigates and simulates the wide bandgap characteristics of lithium niobate photonic crystals. By using finite difference time domain (FDTD) method, the simulations and investigations of the photonic bandgap in a hole-shaped lithium niobate on insulator silica is provided in this paper, through controlling the ratio among the lattice constant, the radius of the air hole layer and the thickness of lithium niobate layer. The results indicate that the radius of the air hole and the thickness of the lithium niobate photonic crystal will affect the center wavelength and bandwidth of the photonic crystal bandgap. And when the ratio of the radius to the lattice constant is about 0.35, by adjusting the thickness of the lithium niobate, a lithium niobate photonic crystal with a wide bandgap of 1387 nm-1726 nm is obtained. Based on this optimization results, the lithium niobate photonic crystal cavity with high Q factor, and also the lithium niobate photonic crystal optomechanical cavity can be achieved.","PeriodicalId":422383,"journal":{"name":"2022 Photonics & Electromagnetics Research Symposium (PIERS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129432144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the three main ways of generating THz waves, vacuum electronics, especially Smith-Purcell radiation (SPR), have been considered as a popular way due to their unsubstitutability to produce relatively high emission power. SPR is a kind of electromagnetic wave radiation that happens when an energetic beam of electrons passes very closely parallel to the surface of a ruled optical diffraction grating. The frequency of radiation waves changes in the upper and lower space of the grating for different electron velocity, satisfying the SPR relationship. In this study, a Fano resonance metasurface was proposed to steer the direction of the SPR waves at the fixed resonant frequency by changing the velocity of the electric beam without varying the geometric parameters or adding extra coupling structure. The maximum emission power always locates at the resonant frequency by utilizing the integration of the Poynting vector. The absolute efficiency is normalized by the kinetic energy of the electrons. There is a great consistence of steering radiation angle about 40 degrees by altering the velocity of electron beam from 0. 6c to 0. 95c both in theoretical analysis and effective surface current simulation, where c is the speed of light in vacuum. Our study indicates that the proposed structure can produce direction-tunable THz radiation waves at resonant frequency by varying the velocity of the electric beam, which is promising for various applications in compact, tunable, high power millimeter wave and THz wave radiation sources.","PeriodicalId":422383,"journal":{"name":"2022 Photonics & Electromagnetics Research Symposium (PIERS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126823762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is applied in order to predict the response of the shielded TWP/twinax cables by obtaining the induced common-mode (CM) and differential-mode (DM) currents due to external electromagnetic interference. Therefore, the field-to-wire coupling to the outer shield is solved by applying the transmission line model. After that, the transfer impedance and admittance of the shield with line apertures are used to model the coupling from the outer shield to the inner wires.
