Polarization dependence on electromagnetic scattering of perfectly conducting concave corners by magnetic field integral equations

The magnetic field integral equation formulation is used for both horizontally and vertically polarized incident waves. The method of moments together with the conjugate gradient solution technique, is then implemented on a personal computer to solve the induced current on the conductor surfaces and the far-field scattering coefficients. Numerical computations are executed for a conductor of L shape. The induced current near the concave corner is compared with that near the convex corner for both polarizations. Also presented are the polarization dependences on backscattering coefficients of the L conductor for various frequencies and incident angles
