Intensity on axis I0, spin angular momentum (SAM) and orbital angular momentum (OAM) of rotating gyrotron TE modes in circular waveguides.
| Mode Family | I0 (Intensity on Waveguide Axis) | SAM (Circular Polarization) | OAM |
|---|---|---|---|
| TE0,n | no (Annual Intensity Pattern) | no (s = 0) | no (l = 0) |
| TE1,1 | yes | yes (s = 1) only RHCP | no (l = 0) |
| TE1,n (n >1) | yes | yes (s = ± 1) | no (l = 0) |
| TEm,1 (m >1) WGM | no (Annual Intensity Pattern) | yes (s = 1) only RHCP | yes (l = m – 1) |
| TEm,n (m,n >1) | no (Annual Intensity Pattern) | yes (s = ± 1) | yes (± l = ± m ∓ 1) |
