Summary: The book is devoted to the synthesis problems that arise in the theory and design of radiating systems (antennas). The desired amplitude characteristics are input data in a synthesis problem. A synthesis problem belongs to a class of inverse problems and its aim is to determine a distribution of current or fields in an antenna, which produces the amplitude radiation characteristic as close as possible to the desired one. Freedom of choice of phase distribution of the desired radiation pattern (RP) — as a rule, this is amplitude or power RP — is used as an additional possibility of better approximation to such RPs. The different types of antenna and arrays are studied here as the radiation systems under consideration. A special class of problems related to acoustic and electromagnetic scattering on a set of bodies (particles) of small size is discussed. The constructive procedures of creating the inhomogeneous materials with specific properties are proposed.
