2 Waves in cylinderIn a waveguide whose cross-section is uniform along z-axis, variation of E, H is proportional to exp(-j z).In a waveguide, transverse E and H can be obtained from Ez and Hz.
3 TM, TE modeTM mode : Electromagnetic wave modes with Hz=0 are called TM modes (Transverse Magnetic). Those modes can be found from Ez.TE mode : Electromagnetic wave modes with Ez=0 are called TE modes (Transverse Electric). Those modes can be found from Hz.
