DYNAMICS OF MICROWAVE-INDUCED CURRENTS IN IONIC-CRYSTALS

The recent theory of averaged ponderomotive action of microwave fields in solids is expanded to describe quasistationary ionic currents driv en by that action. Several limiting cases are explored io detail, and in all cases the effect is shown to depend upon the interfacial proper ties of the ionic crystal. Experimental results on the dynamics of the microwave-induced currents in AgCl and NaCl are presented. Agreement between experiment and theory provides further and stronger evidence f or the general validity of the theoretical model.
