Abstract The finite-difference time-domain
(FDTD) method was used to derive electromagnetic field distributions in a
mass-produced microwave oven where the particular influence of the magnetron
output antenna in a short feeding waveguide was considered or not considered.
It was confirmed in visual and quantitative comparison that the influence of
the magnetron antenna geometry is negligible. A procedure for reduction of
uneven heating is also discussed, using an approach of oven development as a
practical example. Key Words: Finite-difference
time-domain method (FDTD), Heating pattern, Magnetron, Microwave oven. |
