Hello,the hollow waveguide bellow has a=109mm b=43mm L=100mm Er=1
from the formula bellow
For TE21 i get cutoff frequency of 4.4Ghz as shown bellow.
I have defined both port on waveguide ends as shown bellow
but as you can see from simulation result is get m=2 n=1 at cutoff frequency of 2.8Ghz.
Where did i go wrong?
Thanks.
