摘      要：The electromagnetic wave enhanced transmission(ET)through the sub-wavelength aperture was an unconventional physical phenomenon with great application *** was important to find a general design method which can realize efficient ET for arbitrary-shaped *** achieving ET with maximum efficiency at specific frequency through arbitrary-shaped subwavelength aperture,a topology optimization method for designing metamaterials(MTM)microstructure was proposed in this *** MTM was employed and inserted vertically in the *** description function for the arbitrary shape of the aperture was *** optimization model was founded to search the optimal MTM microstructure for maximum enhanced power transmission through the aperture at the demanded *** MTM microstructures for ET through the apertures with different shapes at the demanded frequency were designed as *** simulation and experimental results validate the feasibility of the *** regularity of the optimal ET microstructures and their advantages over the existing configurations were discussed.
