This arrangement provides a remarkably simple beam steering control system replacing the complicated array of computer controlled phase shifters traditionally used for this purpose. The book also describes a large number of laboratory demonstrations that have been reported over the past three decades that experimentally verify the various aspects of the theory. The theory is initially presented using a linear approximation permitting derivation of much of the array behavior analytically. Then, at a deeper level, a nonlinear formulation is used to obtain, computationally, more detailed aspects of the array behavior. The primary purpose of the book is to gather the salient results of the past ten to fifteen years of research in this area into one convenient volume providing both a tutorial explanation of this approach to phased array control and a guide to the literature on the subject"--$cProvided by publisher. 410 0$aJPL deep-space communications and navigation series ;$v11 606 $aAntenna arrays 606 $aElectric networks, Active 606 $aNonlinear oscillators 606 $aCoupled mode theory 615 0$aAntenna arrays. 615 0$aElectric networks, Active. 615 0$aNonlinear oscillators. 615 0$aCoupled mode theory. 676 $a621.382/4 686 $aTEC008000$2bisacsh 700 $aPogorzelski$b Ronald J.$01698671 701 $aGeorgiadis$b Apostolos$01656351 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910807179403321 996 $aCoupled-oscillator based active-array antennas$94080331 997 $aUNINA
