Abstract

By using of high-resolution Terahertz time-domain spectroscopy, we show that both the fundamental and higher-order Mie resonances can be excited in both magnetic and electric modes with in the one-dimensional dielectric grating. Furthermore, their highly sensitive capability dependent on the frequency red-shift, line broadening, and transmission decreasing were investigated with increasing refractive index and absorption strength of the surrounding media.
