FDTD Hard Source and Soft Source Reviews and Modifications
By
Progress In Electromagnetics Research C, Vol. 3, 143-160, 2008
Abstract
We intend to study two kinds of sources known as Hard Source and Soft Source, which are the simplest kinds of sources used in FDTD. We introduce an exact method to control the direction of propagation of a plane wave which can be either a hard source or soft source. Also we show that a simple implementation of a soft source in the Yee algorithm causes an undesired propagation which can result in incorrect answers. To remove this error we suggest a method for different kinds of sources and modes.
