Study on Sensing Performance of MDM Waveguide Coupled with the Square Cavity Containing a Rectangular Groove
In order to realize tunable multichannel high sensitivity refractive index sensing, a square resonator connected with a Rectangular Groove (RG) is proposed to couple with the highly compact Metal-Dielectric-Metal (MDM) waveguide containing double metal baffles.The transmission spectrums of the proposed waveguide structure have been calculated by th
