dc.description.abstract	We discuss the transmission characteristics of a microscale dielectric waveguide device with a deep groove and an embedded metallodielectric grating illuminated by a continuous wave ofTM and TE modes at low terahertz frequency. To study its performance we solve numerically the correspondin& Maxwell equations by means of finite difference time domain method with uniaxial perfectly match layer u its boundary condition. By varying the angle of incident. grating filling factor and refractive index of anatyte in the deep groove. it is found that the device exhibits a sigmfic;mt trammiss1on enhancement for the TM mode due to the existence or surface plasmon interaction. We also demonstrate its potential application as a biosensor device.	en
