中文摘要	transmission of electromagnetic wave in a heavily doped n-type gaas film is studied theoretically. from the calculations, an extraordinary transmission of p-polarized waves through the film with subwavelength grooves on both surfaces at mid-infrared frequencies is found. this extraordinary transmission is attributed to the coupling of the surface-plasmon polariton modes and waveguide modes. by selecting a set of groove parameters, the transmission is optimized to a maximum. furthermore, the transmission can be tuned by dopant concentrations. as the dopant concentration increases, the peak position shifts to higher frequency but the peak value decreases.
