The book is the first one where the properties of these fields are investigated in details. The properties have the important significance for the antenna synthesis, body shape reconstruction and other diffraction problems. The material of the book lies in the meetingpoint of the antenna theory, highfrequency electrodynamics and inverse scattering problems.The author is an internationally renowned investigator in the field o 606 $aElectromagnetic fields$xMeasurement 615 0$aElectromagnetic fields$xMeasurement. 676 $a511.4 676 $a530.141 700 $aKat?senelenbaum$b B.
