论文摘要
我们开发一种紧凑的理论，可以应用于各种时变的分散材料。连续的波反射和传输系数被等效的操作员表达式取代。除了将这种方法与现有的数值和分析技术进行比较之外，我们还发现这些操作员的特征函数代表了与时间变化，分散材料相互作用后不会改变其光谱的脉冲。此外，这些操作员的极点代表了系统的非时代谐波结合状态。
We develop a compact theory that can be applied to a variety of time-varying dispersive materials. The continuous wave reflection and transmission coefficients are replaced with equivalent operator expressions. In addition to comparing this approach to existing numerical and analytical techniques, we find that the eigenfunctions of these operators represent pulses that do not change their spectra after interaction with the time-varying, dispersive material. In addition, the poles of these operators represent the non-time harmonic bound states of the system.
