Application of analogical thinking in constructing light transmission theory of temporal multilayer media
The multilayer media theory and the transmission matrix method are introduced in detail in Princi-ples of Optics,which is a classic textbook for graduate students majoring in optics and physics.Due to the duality of time and space,in this paper,the propagated characteristics of light in the temporal multilayer media whose ma-terial parameters change with time is mainly expounded and the form of transmission matrix in the temporal multilay-er media is deduced.Finally,by comparing the transmitted and reflected coefficients of temporally periodic multi-layer media and spatially periodic multilayer media,the connection and difference between them are deeply dis-cussed.
