摘要: A microstrip ring resonator (MRR) is perturbed by overlaying mug grains (Phaseolus Radiatus Linn.), having different moisture contents (7–42%), at eight angles. Out of the two orthogonal degenerate modes (even and odd) MRR, only even mode sensitive to strength perturbation (grain moisture). The overlay angle moisture-dependent factor reported. results are compared with reported Yogi et al. [16]. © 2002 Wiley Periodicals, Inc.
