Optimization of the Optical Properties of Cuprous Oxide and Silicon-Germanium Alloy Using the Lorentz and Debye Models

다국어 초록 (Multilingual Abstract)

The modeling parameters of cuprous oxide (Cu2O) and silicon-germanium (Si-Ge) alloy for the single-pole Lorentz model and the single-pole modified Debye model (MDM) are optimized and presented. A nonlinear optimization algorithm has been developed in order to optimize the parameters such that they are applicable to a wide frequency range. The obtained parameters have been used to determine the complex relative permittivity of the materials and compared with the experimental values. A very good agreement has been observed between the experimental values and the optimized parameters in the case of both the material models. The associated root mean square (RMS) deviations have been found to be as little as 0.15 and 0.08 for the Lorentz model and 0.1638 and 0.3710 for the modified Debye model respectively.
