A novel terahertz nanofilm sensor consisting of toroidal dipole bound states in the continuum (TD-BIC) inspired Fano resonance metasurface is proposed and investigated, which exhibits both TD character BIC feature. When mirror symmetry unit cell was broken, excited demonstrated by anti-aligned magnetic dipoles calculated scattering powers mode verified with quality factor satisfying inverse square law.

A novel metallic toroidal dipole (TD) metasurface driven by Friedrich-Wintgen bound states in the continuum (FW-BIC) is theoretically proposed for terahertz (THz) sensing. By tuning middle gap distance without breaking symmetry of unit cell, FW-BIC and quasi-BIC mode can be excited via resonance coupling between modes. Based on cyclic distribution anti-aligned magnetic dipoles calculated scattering powers, TD demonstrated qualitatively quantitatively; also verified far-field transmission...
The correction of chromatic aberration is essential for promoting broadband imaging systems, which can be accomplished by recently proposed achromatic metalenses (BAMs) in a more compact and efficient way compared to that traditional optical lenses. However, current BAMs are limited the fixed functionality severely hinders their potential applications. In order address such limitation, continuously varifocal metalens (CVBAM) converging THz waves employing thermally tunable material indium...
In this paper, we investigate several possibilities to increase the efficiency of hybrid automatic retransmission request (HARQ) for multi-input multi-output (MIMO) systems. At receiver side, two HARQ combining schemes, namely pre-combining and post-combining, are discussed analyzed. We show that is superior post-combining. addition, propose a transmission technique, termed basis hopping, which improves diversity gain especially in slow fading channels. demonstrate use conjunction with...

Abstract Artificial intelligence algorithms based on deep neural network (DNN) have become an effective tool for conceiving metasurfaces recently. However, the complex and sharp resonances of will tremendously increase training difficulty DNNs with non-negligible prediction errors, which hinders their development in designing multifunctional metasurfaces. To overcome obstacles, interaction mechanisms between meta-atoms terahertz (THz) waves via multipole decomposition are investigated to...
Abstract With the advances of micro/nano fabrication technology, metasurface has become an alternative to design functional devices for manipulating electromagnetic wave. Metalens is one basic that can be applied in various fields. Currently, polarization measurement based on metalens arrays been widely investigated, but most them only work normal incident wave due limited field - view metalens. Herein, a dielectric wide angle array (WMA) terahertz detection presented. The WMA composed three...
A simple all-dielectric metasurface with symmetric structure, exhibiting strong toroidal dipole (TD) resonance and ultrahigh quality factor (Q-factor), is proposed. The physical mechanisms of the TD are investigated by calculating electromagnetic field scattering power multipoles. Simulated results demonstrate that Q-factor up to 3.71 × 104 corresponding figure merit 636.7. Moreover, can be excited under both x- y-polarized incident terahertz waves due structure. remarkable performances make...
Abstract The non-radiative bound states in the continuum (BIC) have attracted much attention achieving theoretically infinite quality (Q) factor. In this paper, a dielectric terahertz metasurface with C 4v symmetry is proposed, and toroidal dipole resonance easily obtained under incident plane wave. Moreover, by slightly tuning asymmetry parameter δ to break in-plane of structure (side length perturbation), magnetic BIC mode radiates as quasi-BIC (QBIC) extremely narrow linewidth ultrahigh Q...
Metasurfaces that can effectively manipulate electromagnetic waves provide a novel solution to realize efficient terahertz functional devices. However, the chromatic aberration of metasurfaces is remarkable challenge for their extensive applications. Multi-functional are highly desirable in practical Here, we demonstrate polarization-multiplexing achromatic working regime based on anisotropic meta-atoms which exhibit form birefringence. Specifically, metalens frequency range from 0.8 THz 1.2...

Self-focusing is a well-researched phenomenon. Nanoscale spots can be achieved through self-focusing, which an alternative method for achieving high-density data storage, high-resolution light imaging, and maskless nanolithography. Several research groups have observed that self-focusing reduced to nanoscale levels via incident laser power manipulation. analyzed by solving the nonlinear Schrödinger equation finite difference time domain method. However, both procedures are complex...
