Incident wave and unidirectional wave source implementation in Crank-Nicolson scheme for one-dimensional Maxwell's equations

This paper introduces source implementation for Crank-Nicolson based Finite-Difference-Time-Domain method for one-dimensional Maxwell's equations. Two types of sources are developed, namely, an incident wave source which propagates disturbance in both positive and negative directions in one-dimension and another a unidirectional wave source for one-direction propagation.
