Abstract
Electromagnetic simulation of the quality factor measurement was compared to the measurement with a network analyzer. Scattering matrix S21 obtained from the network analyzer was compared to the S21 obtained from the simulation. From electric field distribution, the dominant resonant TE01d mode could be easily determined. The effects of the pore and the conductive inclusion inside the dielectric were investigated. The quality factor decreased with the pore and the second phase in the dielectrics. The decrease of quality factor is more significant when dielectric have conductive inclusions inside the dielectric. Due to the limitations in computer resources and analysis time, the size of the inclusions inside the dielectrics in simulation are not actual size. # 2001 Elsevier Science Ltd. All rights reserved.
