In this paper, we proposed a terahertz (THz) metamaterial sensor, which consists of an array with two mirrored double split ring resonators (DSRRs) in one unit cell deposited on lossless polyimide substrate. The THz spectral response show that when the DSRRs are mirror symmetric and center simultaneously, types symmetry-protected bound states continuum (BICs) can be generated incident polarization unchanged. When gaps short or long arms DSRRs, different modes BIC observed. By breaking...
It is generally accepted that the bound states in continuum (BICs) are usually realized a one-dimensional system by TM-polarized light incident at Brewster's angle. However, optimal BICs can be achieved only under specific and polarization angle, which poses challenges to its experimental implementation. Serving this purpose, we design composed of an anisotropic material (AM) embedded photonic crystals (1D-PhCs), demonstrating both TE TM waves realize BICs. Moreover, existence does not hinge...
This work has demonstrated the feasibility to modulate refractive index of YAG crystal at variable depths via electronic energy depositions argon ions. Surface and buried cladding waveguide layers various geometries were successfully created, which are capable effective light confinement guidance infrared waveband 1064 nm. Refractive profiles irradiated reconstructed in a reasonable manner according variations stopping powers. Information about structural damage level ion given by measured...
