Zo. Alhekail et Wd. Burnside, A HYBRID METHOD FOR COMPUTING THE SCATTERED FIELDS FROM COMPLEX STRUCTURES, IEEE transactions on antennas and propagation, 42(6), 1994, pp. 847-852
A new hybrid method that removes typical discontinuities and singulari
ties of UTD solutions is described and applied to scattering by comple
x structures. The scattered fields from the structure are first comput
ed on a surface S enclosing it. Then these fields are used to compute
an equivalent set of electric and magnetic currents, which are then us
ed to find the scattered fields from the structure. This method can ex
tend the ability of available UTD computer codes to solve for the scat
tered fields from structures that need special treatment and are not s
olvable through direct UTD means. Good agreement is shown between this
new hybrid method and moment method results as well as measurements.
