An enhanced near infrared transmission through periodic H-shaped arrays in metallic thin films is presented.The sample is fabricated by electron beam lithography and reactive ion etching system.The 0.5-mm-thick quartz substrate is deposited with a 120-nm-thick Au film and a 5-nm-thick chromium adhesion layer.The overall size of the sample is about 40×40 μm2,which is composed of 30×30 periodic H-shaped arrays.The period of the H-shaped lattice is 1.1 μm.The arm length of H-shaped is 500 nm and the line width is 120 nm.A broad transmission band centered at about 1.6 μm is found and the transmission coefficient can be as high as about 16.3% for a line width of 120 nm.A simulation by using transfer matrix method (TMM) reproduces quite well the obtained transmission spectrum.Polarization measurements of H-shaped arrays are also demonstrated.The results prove the important role of localized surface plasmon (LSP) in enhanced transmission through the special structure.
