An a × b rectangular waveguide is operating in four different modes as TM11, TM12, TM10 and TE20. If a = 2b then the ascending order of the operating modes for their cut-off frequencies will be:
1
TE10 < TE20 < TM11 < TM12
2
TE10 < TM11 < TE20 < TM12
3
TM12 < TM11 < TE20 < TE10
4
TE10 < TE20 < TM12 < TM11
