Understand H-plane filter has the same "B" dimension, why does it called "H-plane", relating to Magnetic field not changing on the plane?

H-plane waveguide structure only support TEmn mode, which has Ex, Ey, Hx, Hy, Hz vector, correct? So the magnetic vectors are on all the directions....

So why called "H-plane"??

Thanks.
 

Looking at linear polarized waveguide modes, you'll realize that they involve H- and B-planes which contains the vector of H respectively B-field with zero fieldstrength perpendicular to the plane.

FvM, thanks for the reply.

Linear Polarized mode, you mean for example TEm0 mode? Yes, I understand for those modes, H-filed only has X and Z vector (assume XZ plane is the so-called H-plane)

However, We know H-plane Filter/discontinuity also supports other TEmn mode, e.g. TE11 mode, which has H-field with Y-vector, so no Zero field strength perpendicular to the plane.

What do you think?
