Hi,
I'm looking for ways to re-size a microwave
oven (similar to a commercial domestic MW oven)
for some food processing applications.
Assume:
rectangular waveguide (a=9.5 cm, b= 5.5 cm); incident
frequency: 2.45 GHz.
Suppose we fix two dimensions
of the cavity and modify the length. The objective
is to have minimum power reflection though the port
(S11) so that maximum energy efficiency can be obtained.
If we use RF calculator, we can have various cut-off
frequencies depending on the modes. What should
be the guidelines (cut-off frequency, modes etc)
so that we can achieve the design objectives?
Thanks and regards,
FoodRF
