Book Description
The topic of scattering and propagation in random media is one that has implications for the design, development and operation of most military systems that radiate energy as a means of accomplishing their funtion. Primary emphasis is on scattering and transmission in the atmosphere; however, other related random medium effects are not excluded. Modern methods of characterizing random media, mathematical methods and their applicability, effects on electromagnetic waves and the interpretation of these effects to specific system applications are described. The region of the spectrum considered is essentially unlimited and ranges from very long waves to optics. The performance of existing surveillance communication and navigation systems as well as the design of future systems is influenced by the propagation of energy via random media. An understanding of the nature of the medium and its impact on system design and performance is essential to the NATO community.

Book Description
Excerpt from The Diffraction of Oblique Surface Waves by a Right-Angle Bend In this paper we discuss the diffracted field that arises when an incident electromagnetic surface wave strikes the edge of a right - angle bend at an oblique angle. One face of the bend which supports the surface wave is an impedance plane and the other face is a perfector conductor. The edge of the bend may be either parallel or perpendicular to the perfectly conducting direction of the impedance plane. The diffraction of normally incident surface waves by a right - angle bend and its implication for surface.

Book Description
The diffracted field that arises when an incident electromagnetic surface wave strikes the edge of a right-angle bend at an oblique angle is investigated. One face of the bend supports the surface wave and the other face is a perfect conductor. This diffraction problem is related to the scanning surface wave antennas. An analysis of oblique surface waves on an infinite impedance plane is first presented graphically. We treat two cases. In one case the edge of the bend is parallel, and, in the other case, perpendicular, to the perfectly conducting direction of the impedance plane. When the surface wave is incident normally, these special cases reduce to the normal TM and TE surface waves respectively. The mathematical formalism of the first case may bb y be reduced to that of a two dimensional TM problem which has been solved previously. The second case involves two coupled mixed boundary conditions and is exactly analyzed in detail. The effect of the obliquity on the reflection coefficient and the radiation pattern under various conditions is discussed. (Author).
