This chapter will study edge waves scattered from an edge of a concave body. To do this, 3.1 will examine the plane wave excitation of a wedge-shaped horn. The main objective here is to determine the field radiated by the nonuniform/fringe current. The results of this section are used in subsequent sections to calculate the radar cross section of a concave bodies of revolution.

Chapter Contents:

  • 3.1 Field Inside a Wedge-Shaped Horn
