The main drawbacks of microwave heating of bioproducts (e.g. foods) are associated with its nonuniform heating patterns. The objective of this work was to derive optimal operating policies for microwave combination ovens in order to achieve better uniformity of temperature and/or quality. The corresponding optimal control problems were stated considering the microwave power and the oven tempera...

Aim: This study investigated the tooth movement of complete dentures processed by microwave activation and conventional processing method in water bath. Methods: Twenty maxillary complete dentures were fabricated and randomly assigned to 4 groups (n=5): Group I: Classico conventional heat-curing acrylic resin processed by microwave polymerization; Group II: Classico resin processed in water bat...

Conventionalmicrostriplowpass and bandpass filters such as stepped-impedance filters, open-stub filters, semilumped element filters, endand parallel-coupled half-wavelength resonator filters, hairpin-line filters, interdigital and combline filters, pseudocombline filters, and stub-line filters are widely used in many RF/microwave applications. Modern RF and microwave communication systems, spec...

In the present study, recent progress in using microwave energy to enhance oxidative degradation of pollutants of poor biodegradability in industrial wastewaters is reviewed and evaluated, in order to assess the potential of microwave-induced oxidation as effective and viable remediation technique, alternative to conventional treatment procedures. Microwave radiation is actually emerging as an ...

This paper describes the architecture of a microwave radar system intended for imaging concealed objects under clothing as a subject walks through the inspection area. The system uses the principle of inverse aperture which is achieved by a person’s movement past a stationary microwave sensor array. In the system, the vertical resolution is achieved by arranging microwave sensors vertically whi...
