The utility model discloses an embedded metal cylindrical hole array periodic structure equal from excimer wave filter, metal film have and arrange a plurality of the same round hole that link up the metal film that becomes the hole array, and downthehole medium be the air, and the long wide of unit cycle equals. Plane light is by last or lower vertical incidence. Every kong zhongjun has inlayed a metal cylinder, and metal cylindrical diameter is lighter than the aperture, and the two is gapped, and the preferred is the two central line coincidence. The cylinder height is less than or equal to the height in hole, and cylindrical top surface and bottom surface all do not surpass the upper and lower surface of metal film, and the preferred is the upper surface looks parallel and level of capital face and membrane. Be less than the hole height when the cylindrical height, the below adds the medium liner of adjustment position. Medium liner and the same dielectric cylinder of metal circle column diameter, and coincide with metal cylindrical center line. This novel and current hole array etc. Is compared from the excimer wave filter, and metal cylindrical material, position, radius, high structural parameters are adjusted in the optical transmittance reinforcing, and the optional passs through the position at peak.
