Split modes in asymmetric microstrip ring resonator by flexible perturbation

摘要: The microwave microstrip ring resonator (MRR) is perturbed by a flexible, nondestructive method of keeping cross and partial overlays Al2O3 strips. splitting the resonance curve observed with amplitude variations as expected theoretically, but not below critial perturbation. Further empirical relations are reported for first time, odd-mode frequency (fro) even-mode (fre) variations, giving fre changes proportional to perturbation, fro being independent same. © 1998 John Wiley & Sons, Inc.
