Popis:	In this paper, we have investigated the optical properties of one-dimensional periodic structure of dielectric materials with defect of liquid crystal (LC) sandwiched with two silver (Ag) layers. The transmission, reflection and absorption properties of considered periodic structure have calculated theoretically using transfer matrix method (TMM). Our study reports that the tunability of absorption defect peak of the defect periodic structure is achieved by the variation in the incident angle of electromagnetic wave. The obtained result suggests that such defect periodic structure may be used as tunable sensor and filter devices.
