A theoretical analysis of the relationships shown from the general experimental results of scattering parameters s 11 and s 21 – exemplified by the film of BaFe12- i Ce i O19/polypyrene with i = 0.2, 0.4, 0.6
Abstract The common practice of applying reflection loss to material is incorrect as it can only be applied to film. Also the dominant theory of impedance matching should be replaced by wave cancellation theory. Here, we show that experimental data obtained from microwave absorption by the film of the titled composite can be successfully analyzed theoretically from our new theories. Formulae for the scattering parameters s 11 and s 21 of the film have been derived based on the wave addition model which clearly differentiates between microwave absorption mechanisms from interface and film. The experimental values, the patterns from s 11 and s 21, and the relationships between the patterns from the experimental values have been reproduced and interpreted both quantitatively and qualitatively from the new perspective. This specific new analysis for the verification of the new theory involving a large data set provides a clear indication that the conclusions obtained are not only valid for one unique system but are of general applicability. Thus, the new theory has been verified and can be used to reveal the mechanisms of microwave absorption by material and device. The successful interpretations are contrasted with the inadequacies of previous applied methods involving reflection loss and impedance matching.
期刊介绍:
The Journal of the Microwave Power Energy (JMPEE) is a quarterly publication of the International Microwave Power Institute (IMPI), aimed to be one of the primary sources of the most reliable information in the arts and sciences of microwave and RF technology. JMPEE provides space to engineers and researchers for presenting papers about non-communication applications of microwave and RF, mostly industrial, scientific, medical and instrumentation. Topics include, but are not limited to: applications in materials science and nanotechnology, characterization of biological tissues, food industry applications, green chemistry, health and therapeutic applications, microwave chemistry, microwave processing of materials, soil remediation, and waste processing.
