Analysis of dielectric resonator cavities using the finite integration technique

De-embedding intrinsic parameters of high-Q dielectric resonators from noisy measurements

“…Bandwidth enhancement (36%) of the monopole antenna by using a parasitic normal-mode helix was reported [5]. Bandwidth operation (44%) of a planar monopole antenna was also researched [6], and a top-loading monopole antenna was reported in [7]. This antenna obtained a small size, but its operational frequency characteristic is a very narrow bandwidth (a few percent bandwidth).…”

“…Various methods have been advanced for the experimental characterization of DRs [1][2][3][4][5][6]. DRs have also been analyzed by rigorous numerical methods, such as the finite-integration technique [7] and the method of moments (MoM) [8]. A major problem in DR characterization, from either measurements or simulations, is to extract the unloaded Q by de-embedding the coupling circuitry from the overall measurement [9].…”

New recovery error indicator for adaptive finite-element analysis on waveguiding structures

“…The reference value, i.e., that obtained in the eighth step of the adaptive FEM, was . The phase constant obtained by means of the commercial tool MAFIA (finite-integration technique [23], 100 000 nodes) was . The sequence of adapted meshes throughout the process (Fig.…”

A Hybrid Numerical Method for Loaded Highly Resonant Single Mode Cavities

“…The determination of this critical length is a difficult problem in itself and has been addressed by other authors [9,10]. The technique we develop is along similar lines and requires a single numerical (e.g., FDTD) calculation for a sample in an infinite and homogeneous waveguide, and an approximation to the reflection coefficient for an iris.…”
