A polynomial model of transmission and reflection of electromagnetic monochromatic plane waves in lossy, non-magnetic multilayer thin films subjected to an external transverse voltage

Simulation of the electrical and optical response a multilayer thin film composed lossless material coupled with adjacent lossy in an alternating arrangement when applying transverse voltage across is conducted using polynomial approach. The modelling lossy–lossless generalization our previous work on made up lossy–lossy materials. It propagation matrix electromagnetic wave that governs its propagation, while interface represents coupling between layers at interface. present solution models as effective capacitor constructed from series capacitors, every layer being considered to next. A can affect amounts electric charges accumulate ‘capacitors’. model describe nonmagnetic, With aid home-developed code implementing model, reflection transmission Ge/MgO films are simulated. By tuning potential, geometrical parameters arbitrary film, capable predicting nontrivial responses terms $$T\left(\lambda \right), R\left(\lambda {\phi }_{T}\left(\lambda }_{R}(\lambda )$$ . serve useful tool for designing optimizing lossless-lossy or lossless-lossless deliver desired functions.
