Excitation of the groundwave,de. At that point, a fraction of the incident field is converted to a groundwave mode, and the rest continues. Analagous to reflection and transmission coefficients, an excitation coefficient gives the fraction of the incident field that is converted to the groundwave mode.

Excimer Laser Projection Patterning,Although to date I have applied the GTD to only a concentric ionosphere, the basic importance of the method is its applicability to calculation of diffraction by the earth of radio waves reflected from an ionosphere that has realistic horizontal gradients.

Application of the GTD to a concentric, isotropic ionosphere,A concentric, isotropic ionosphere is probably the simplest example of an ionospherically reflected wave diffracted by the earth. It is also probably one of the few cases where application of the GTD gives an analytical solution. It has the further advantage that a rigorous solution exists for comparison.

Discussion,Although to date I have applied the GTD to only a concentric ionosphere, the basic importance of the method is its applicability to calculation of diffraction by the earth of radio waves reflected from an ionosphere that has realistic horizontal gradients.

Introduction, ionosphere did not exist: 1) Analytical fullwave solutions exist only for particular geometries. The solution for a spherical geometry (i.e., a homogeneous, isotropic, concentric, sharply-bounded ionosphere) has been particularly well developed [WATSON, 1919; BREMMER, 1949; WAIT, 1960, 1961; JOHLER

The path of a surface diffracted ray, Fermat’s principle, they obtain a path of the type SPQO in figure 1, i.e., the path of a string stretched between the transmitter and receiver in contact with the sphere. They also obtain paths that wind around the sphere many times. The straight line segments are geometrical optical rays, and the
