Abstract :
The authors introduce an approximate but computationally single technique for calculating the natural current and backscattered field response of an arbitrarily shaped thin wire scatterer. A single one-term resonant current approximation is shown to yield excellent results for the natural frequencies of perturbed straight wires and circular loops. Comparison with the measured current response of a compound wire target validates the simple theory
