Study on Development and Application of Microwave Technology

Abstract

<p>Microwave technology in just a few decades has penetrated into all walks of life, to social development and people's life had a profound impact. On the basis of the development of the microwave, the details of the mechanism of microwave heating and microwave sterilization of both technologies, and microwave heating conditions and characteristics of clarification, in addition, also includes microwave technology is widely used in various fields, while microwave technology for the existing problems are analyzed, and the prospects for the development of microwave technology is also discussed.</p>

“…Modeling of infiltration of liquids in porous media is a well-studied subject, especially in the field of hydrology where it is used to model seepage of water through porous soils and rocks. 29,30 The physics of resin flow into a mold under pressure is similar to the seepage problem and so similar approaches have been used also to model the flow of resin into a mold containing fiber mats. 23,[31][32][33][34][35][36][37][38] The models are used in these cases to determine the resin flow front and mold filling times corresponding to different infiltration conditions.…”

“…Microwave heating is a heating method through which the sample absorbs microwave energy and converts it into heat energy so that the whole body heats up at the same time. 29 Under the action of the rapidly changing highfrequency electromagnetic field, the polar orientation of molecules in the heated medium will change with the change of the external electric field, resulting in molecular movement and mutual friction effects. The energy of the microwave field is converted into heat energy in the medium, which increases the temperature of the material.…”
