TE TM modes




Q: TE/TM at planar interfaces (with respect to incident plane)?

TMP: TM=p; TES: TE=s

Q: TE/TM in Mie cylinder (with respect to the cylinder axis)?

  • Transverse Electric (TE) means E perpendicular to cylinder infinite axis, H along cylinder axis.
  • Transverse Magnetic (TM) means M perpendicular to cylinder infinite axis, E along cylinder axis.

TE x-pol, TM z-pol

Q: TE/TM mode in Mie sphere?

In normal setting, x-polarized incident, propagates along z-axis,

Example a= 500 nm, lambda = 407.5

  1. XZ plane (TM mode)

XZ plane, E has component along z-propagation direction, so it is TM mode.

YZ plane (TE mode)

The |E| field plot above shows this is TE mode, E perpendicular to the YZ plane.
