Abstract

The power absorption for a crystal with finite dimensions is calculated when the microwave Hac is applied parallel to the ab-plane. The screening current across the ab-planes induced by Hac excites the transverse Josephson plasma. The calculated absorption spectrum depends sensitively on the dimensions of the ab-plane L due to the interference of the Josephson plasma waves. For L less than a critical dimension L*, which is comparable to the microwave wavelength in the superconductor, there is no absorption peak in the spectrum. For L > L*, the spectrum exhibits distinct resonance peaks whose number increases successively with increasing L. The L-dependence of the spectra is confirmed by the recent microwave experiments made on various size of Bi2Sr2CaCu2O8+δ crystals.
