Transmittance of a dielectric slab using transfer matrix method
(UMT, Lahore, 2021) MUHAMMAD ADNAN
Transfer-matrix method (TMM) in electromagnetic and optics is a powerful and convenient mathematical formulism for determining transmittance of a slab and multilayered structures. A plane electromagnetic wave interacts with the material of a slab or multilayered structure at an angle with the normal. A portion of this light passes through the interface first and then propagates in the material, and finally it leaves out from the material interface carrying information about the material. In the present thesis, we study the transmittances of a dielectric slab and a thin film coated on the substrate using TMM for TE (transverse electric) and TM (transverse magnetic) modes of light. Different parameters such as angle of incident, thickness, permittivity, and permeability of slab or thin-film are used and the results are discussed in the thesis.
