            Abstract : 
The geometrical theory of diffraction by a curved wire is used to calculate the backscattered field from a circular loop of wire at oblique incidence. The scalar cases of hard and soft wires and the electro-magnetic cases of horizontal and vertical polarization are treated. Graphs of the back-scattered amplitude versus angle of incidence are given for ka = 1, 2, . . ., 9 where k is the propagation constant and a is the loop radius.
