The finite-difference time-domain (FDTD) method is arguably the most popular numerical
method for the solution of problems in electromagnetics. Although the FDTD method has …

A modified indirect algorithm for extracting real permittivities from measured resonant
frequencies has been developed. It is based on the perturbation theory along with the …

Microwaves can be effectively used in the processing of industrial materials under a wide
range of conditions. However, microwave processing is complex and multidisciplinary in …

Open dielectric resonators using the FD-TD (finite-difference time-domain) method are
analyzed. Resonant frequencies and quality factors are calculated using Prony's method …

Microwave sintering of ceramics in multimode cavities, particularly the use of picket-fence
arrangements, has recently received considerable attention. Various types of ceramics have …

A modified finite-element technique for the analysis of axisymmetric cavities is presented. In
