Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

Post subject: Resize a microwave oven

I'm looking for ways to re-size a microwave
oven (similar to a commercial domestic MW oven)
for some food processing applications.
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,
