Dielectric properties for selected wall material in the development of microwave-encapsulation-drying

Dielectric properties study is important in understanding the interaction between materials within electromagnetic field. By knowing and understanding the dielectric properties of materials, an efficient and effective microwave heating process and products can be designed. In this study, the dielect...
