| Abstract | ||
| The paper studies the design of Dual Bragg Reflectors with quarter-wave dielectric stacks in the region(8-13µm(for the Oblique incident by using Characteristic matrix theory with the aim of treating the changes ensues by the changes of the incident angles (side displacement in the reflection spectrum in addition to side displacement for the position of the high transmission and the value of the transmission itself). Matching was used in the optical thickness for the filter layers in Oblique incident in relation to vertical incident. An improvement in the filter performance was registered without change in the transmission value. The possibility of increasing the transmission of the optical thickness for the outer layer of design was also studied. The study also shows that it is possible to use matching in the optical thickness with increasing the thickness of the outer layer to reach high transmission for p- and s- polarization.The results illustrate that the modified characteristic matrix method for oblique incidence of light can be considered an active, efficient and simple for design the Minus filter. Also, introducing the concept of “matching” can be considered an alternative analytical design method for different types of polarization keeping the peak transmissio | ||
