The transmission properties of one-dimensional metallodielectric photonic crystals are studied theoretically. The matrix transfer method is used to numerically simulate the transmission through the structure. The result shows that transmission resonances can increase the transmission dramatically and reduce the absorption in a certain extent. By selecting the thickness of Au and MgF₂ layers and the periods number properly,a pass band whose transmission is above 0.4 in the visible range is obtained and light can hardly pass the structure in other frequency ranges. The structure has high transmission and metal's ad-vantages,so it can be used in many fields as sensor,eye protection devices,heat reflecting windows and liquid crystal displays.
