In sections on acoustic waves in sonic crystals, elastic waves in phononic crystals, and wave phenomena in phononic crystals, he considers such topics as scalar waves in periodic media, sonic crystals, phononic crystals for surface and plate waves, coupling acoustic and elastic waves in phononic crystals, evanescent Bloch waves, and spatial and temporal dispersion

Except for the condition (4), our method allows for arbitrary temporal dispersion. Upon the condition (4), the inverse of the wave impedance Z([omega],r) as well as the refractive index n([omega],r) become linear spatial functions throughout the entire structure
The model is valid for arbitrary temporal dispersion and arbitrary losses, as long as the general mathematical and physical constraints are satisfied.
Conduction block that recovers without development of increased temporal dispersion or other demyelinating features.
There was not an acute demyelization in our patient, because recovery from demyelinating CB is characterized by increased duration of CMAP (temporal dispersion) and slowing of conduction velocity.
The motor responses showed reduction in amplitude in legs but no evidence of demyelination such as conduction block or temporal dispersion
. This pattern of findings in the context of this patient's illness was consistent with acute motor axonal neuropathy (AMAN).
Temporal Dispersion was associated with the involvement of the Schwann cell during the subacute inflammation occurring during a T1R.

Thus, a parabolic approximation of the de Broglie-like equation along the y direction yields a hyperbolic Schrodinger-like equation analogous to that arising in the study of normal temporal dispersion
