The method of hidden rays is applied to the electromagnetic diffraction by composite wedges composed of perfect conductor and lossy dielectric. The E-polarized diffraction coefficients are expressed as a finite series of the cotangent functions, of which the angular period is adjusted to satisfy the edge condition at the wedge tip. The accuracy of the diffraction coefficients is assured by showing how closely the null-field condition is satisfied in the complementary region.
