Abstract :
The problems of scattering elimination and null steering are solved by simple matrix formulation obtained using the antenna and scatterer modes of straight wires. The current distribution and far field expressions were obtained using the equivalent TEM mode theory. Results obtained from these expressions showed very good agreement with numerical results.
