“…The temperature rise in a defined volume is then directly proportional to the dissipated microwave power, which can be inferred from the effective electric field value and the dielectric loss factor. Some results using this approximation can be found for example in Fu and Metaxas (1994), Liu, Turner, and Bialkowski (1994), Dibben and Metaxas (1994), Zhao and Turner (1997), and Sundberg, Kildal, and Ohlsson (1998).…”

SUMMARYIn FDTD analysis, the numerical dispersion caused by the discretization of time and space becomes a problem. Previously, the numerical dispersion was corrected by changing the speed of light. However, such an approach is limited to isotropic meshes. In this paper, a generalized formulation is introduced such that this correction method can also be used in nonisotropic meshes. As an application example, the method is used for the analysis of a large cavity, demonstrating the effectiveness of the method.

“…In 1992, Jia, et al [6] presented a three-dimensional finite element algorithm for studying microwave field and power distributions generated in a multimode cavity. Recently, the finite-element time-domain (FE-TD) method [7] was applied to the analysis of multimode applicators, with regular computational domains, using edge elements. The Finite-Difference Time-Domain method is considered by many researchers to be one of the most accurate and simple for implementing numerical methods when solving electromagnetic problems.…”

Microwave processing of materials is a relatively new technology advancement alternative that provides new approaches for enhancing material properties as well as economic advantages through energy savings and accelerated product development. This paper presents a state-of-theart review of microwave technologies, processing methods and industrial applications. The characteristics of microwave interactions with materials are outlined together with the challenges that difficult to process materials present. To fully realise the potential benefits of microwave and hybrid processes, it is essential to scale-up process and system designs to large batch or continuous processes. This necessitates computational modelling and simulation, system design and integration and a critical assessment of the costs and benefit analysis. Impediments to industrial applications are identified and development opportunities that take advantage of unique performance characteristics of microwaves are discussed. Clearly, advantages in utilising microwave technologies for processing materials include penetrating radiation, controlled electric field distribution and selective and volumetric heating.The aim of the work presented in this paper is to help guide those interested in using microwaves to improve current materials processing. Microwave fundamentals are described to provide a brief awareness of the advantages and limitations of microwaves in the processing of materials. Furthermore, the limitations in current understanding are included as a guide for potential users and for future research and development activities. Examples of successful applications are given to illustrate the characteristics of materials, equipment and processing methods applicable to industrial microwaves. Economic considerations are described and costs are provided as guidelines in determining the viability of using microwaves for processing materials.
