A Mathematical Analysis of the Strip-Element Method for the Computation of Dispersion Curves of Guided Waves in Anisotropic Layered Media

Figure 2

Direction dependence of circular frequency $\omega (k,\varphi )$$[{\text{s}}^{-1}]$ at circular wavenumber $k=1000$ ${\text{m}}^{-1}$ for different ratios $E_2/E_1$. As one can see, each mode has its own individual anisotropic behaviour; even the sequence of the wave modes ordered by their frequencies is angle dependant.
