Q1:

To ensure that only dominant mode TE10 is allowed to propagate in an air filled rectangular waveguide, the lower frequency limit and upper frequency limit are

A about 25% above fc for TE10 and 5% below fc for TE20 mode respectively

B about 50% above fc for TE10 and 25% below fc for TE20 mode respectively

C about 25% above fc for TE10 and 25% below fc for TE20 mode respectively

D none of the above

ANS:A - about 25% above fc for TE10 and 5% below fc for TE20 mode respectively
