An evanescent wave is a wave disturbance which travels along a direction and attenuates along a different direction. Evanescent waves are typically generated when a plane wave obliquely strikes a boundary between two media possessing different materi

The consequence of imposing stationary constraints on first‐order hyperbolic differential systems is analyzed in detail and it is proved that such constraints can be compatible only with systems admitting zero‐speed waves. The definition of const

The problem of oblique incidence of plane waves on a boundary between two linear media is examined in detail especially in connection with generation of evanescent waves. It is shown that, unlike plane waves, evanescent waves are fully determined by

On adopting the usual view that a second order differential system is hyperbolic provided that the equivalent first order one is, a theorem is proved which offers an intrinsic procedure to check hyperbolicity of second order systems. In deducing such

Shock waves and the relevant Rankine-Hugoniot conditions may be inadequate even in simple cases. As an example, the electromagnetic field generated by a point charge, whose velocity jumps from0 to a constant valueυ, not only jumps across a spherical

The compatibility between the objectivity principle and affine constitutive equations for the elastic Cauchy and Piola-Kirchhoff stress tensors with non-zero residual stress is examined. It is found that the Cauchy stress is allowed to be only a cons

A geometrical interpretation of the shear-free condition, required by Robinson's theorem, is given. In particular it is proved that the shear-free condition for a (geodesic) null congruence is necessary and sufficient in order that the null condition
