Title: Internal Resistance of Voltage Source Using the FDTD Technique
Published: November 02, 2009
Abstract: The introduction of the internal resistance of a voltage source is a very effective method for analyzing the electromagnetic characteristics of antennas and microstrip devices using the FDTD technique. However, some trial and error could be accompanied for a proper resistance values to obtain a stable result. This letter proposes the method to reflect a proper internal resistance of source voltage in an FDTD code. The key of this method is to choose a resistance value so that the voltage drop due to an internal resistance is less than the amplitude of a voltage source. The reductions of total computation time steps are shown for various antenna types.
