摘要：

The dielectric properties of LaAlO3 single crystal plates were studied by microwave techniques in a frequency range from 20 to 28 GHz. The measurements were performed using a resonator representing crossed round (cylindrical) and radial evanescent waveguides with the polarization-degenerate fundamental oscillation mode. Various single crystal samples, including those obtained from different manufacturers, exhibit anisotropy in the (100) crystal plane, whereby the permittivity varies within Deltaepsilon = 0.1-0.9.
