For
TM wave, all these three features are also found and thus are not replotted here.
This shifting feature is more salient in the TE wave than
TM wave.
Analogous derivations for
TM wave result in a similar formula with [E.
The above calculations can be used for
TM wave by substituting [p.
i,s] for the
TM wave, where the subscripts i, j and s correspond to the quantities in the incident medium, periodic medium of photonic crystal and substrate respectively.
If a
TM wave is incident on the indefinite medium along its tangential orientation, both the wave vector [k.
For
TM wave the infinitely long cylinder constitute an inductance while for periodic cylinder an additional parallel capacitance is formed in the gaps between cylinders, which gives rise to a resonance visible in [S.
If we analyze the reflected and transmitted waves in detail, we can find that in the case of existence of the Brewster's angle, there is no cross-polarized wave appears in the reflected and transmitted wave when the incident wave is TE wave or
TM wave.
First, at angle near the critical angle (42[degrees]), the critical thickness for obtaining BS in
TM wave is greater than that in TE wave.
In our simulations, a TM line source (along the z axis) is used to generate the
TM wave propagating along the x direction, with the magnetic field polarized along the z axis, as shown in Fig.
The role played by the incident angle is to narrow the resonant shape, especially in the
TM wave.
Depending on the amplitude sensitivity of photo-detectors, the diffraction efficiency of the zeroth-order
TM wave should have a lower limit.
