Closed-Form Scattering by a Class of Skew Trihedral Reflectors

The scattering of a plane electromagnetic wave by a metallic trihedral corner reflector is analyzed, in the phasor domain. Two of the metal planes of the reflector intersect the third plane perpendicularly, and form an angle between them that is equal to π radian divided by an integer. The exact solution is obtained in closed form, and is shown to consist of the sum of a finite number of plane waves.
