Synopsis
Excerpt from Radiation Patterns and Radiation Fields
There are two aspects of this problem of radiation patterns. The first is to prove (5) and express fig) in terms of U(x); the second is to find a func tion U(x) having a given radiation pattern This last problem involves de termining the class cuffunctions f(é), defined on the unit sphere, which.may occur as radiation patterns. This class is not the class of continuous functions nor is it the class of analytic functions; it can best be characterized by considering an associated class of harmonic functions H(x). The order of magnitude of hkx) gives a criterion as to whether or not can be a radiation pattern.

Paperback. Condition: New. Print on Demand. This book explores the asymptotic behavior of scalar radiation fields that satisfy specific radiation conditions. The author introduces spherical coordinates to derive an asymptotic relation that defines the radiation pattern, which is a function representing the angular factor in the leading term of the field's asymptotic expansion. The book establishes necessary and sufficient conditions for a given function to qualify as a radiation pattern. It also determines the smallest possible sphere that contains all the sources for a given pattern. Ultimately, the author provides a criterion for determining whether a prescribed function can be a radiation pattern, enabling the determination of the radius of the smallest sphere enclosing the sources generating the pattern. The book's insights shed light on the relationship between the radiation pattern and the underlying scalar field, offering valuable insights for researchers and students in the field of electromagnetics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781333464103_0
