Trends in Metal-Insulator-Metal-Insulator- Metal Multilayers Built Using Fabry-Perot Cavities

This chapter presents a comprehensive study on the design, analysis, and performance of Metal- Insulator-Metal-Insu- lator-Metal (MIMIM) multilayer stacks. The behavior of these stacks was modeled using the Transfer Matrix Method (TMM), allowing for a detailed investigation into their optical properties under varying parameters such as refractive in- dex, layer thickness, polarization, and angle of incidence. The results highlight significant trends, including the effects of changing the incidence angle and layer thickness on reflection dips and absorption peaks, which exhibit wavelength-de- pendent shifts and intensity variations. These finding are particularly relevant for optimizing selective emitters in thermo- photovoltaic (TPV) systems, where specific resonant peaks are desirable for efficient energy conversion. By adjusting the thickness of the metal and insulator layers, the study demonstrates how precise control over multilayer parameters can enhance performance, particularly through the strategic tuning of Fabry-Perot cavities within the stacks. The insights provided pave way for future applications in photonic and optoelectronic devices.
