    Tamm surface plasmon wave is a surface wave that is confined to the interface between a metal and a one-dimensional photonic crystal, it can be produced by both TM amd TE polarization at any incident angles. In this paper, a device consisted of liquid crystal and distributed Bragg reflector is simulated by using Transfer Matrix Method. First, calculating reflection and transmission coefficient in liquid crystal layer by using electromagnetic boundary conditions. Second, calculating reflectivity by using interface and propagation matrix. Next, when liquid crystal is tuned angle, we analyze refleciotn, band gap and field diagram in simulation. Finally, we discuss the relationship that is between resonance wavelength and Tamm plasmon wave, furthermore, we change the thickness in other layers and discuss their influence to resonance wavelength. In conclusion, this research confirms Tamm Plasmonic device experiment result (NCTU, Dr. Jeng, Shie-Chang) and discuss them
