Abstract: Based on the transmittance matrix (T-matrix) approach, an efficient and stable rigorous coupled-wave analysis (RCWA) method for ultrathin multilayer gratings without solving eigenvalues is ...

Abstract: This paper introduces a new algorithm for solving the matrix Riccati equation. Differential equations for the eigenvalues and eigenvectors of the solution matrix are developed in which their ...

An optical Illusion is a visual trick where our eyes and brain perceive different images from reality. These illusions are a type of visual puzzle that creates a misleading effect on our brain, ...
