This book deals with the EM analysis of closed microwave cavities based
on a three-dimensional FDTD method. The EM analysis is carried out for
(i) rectangular microwave ovens and (ii) hybrid-cylindrical microwave
autoclaves at 2.45 GHz. The field distribution is first estimated inside
domestic rectangular ovens in xy-, yz-, and zx-plane. Further, the RF
leakage from the oven door is determined to study the effect of leakage
radiation on wireless communication at 2.45 GHz. Furthermore, the EM
analysis of the autoclave is carried out based on 3D FDTD using
staircase approximation. In order to show the capability of autoclaves
(excited with five source) for curing the aerospace components and
materials, the field distribution inside autoclave cavity is studied in
presence of aerospace samples. The FDTD based modelling of oven and
autoclave are explained with the appropriate expressions and
illustrations.
