Radial Propagation

A study is made of the radial propagation of axial shear waves in an incompressible elastic solid under finite radial deformation. Basic equations are derived on the basis of Biot’s mechanics of incremental deformations, and analysis is made by the method of characteristics. Numerical examples are given by specializing the initial deformation to two cases: (a) an infinite solid with a cylindrical bore is inflated by all-around tension, and (b) a cuboid is rounded into a ring and its ends are bonded to each other. The influence of the inhomogeneities of such deformations upon the laws of shear wave propagation is presented in the form of curves.

This paper discusses eigenvalues of the electromagnetic field along an infinitely long and conductive circular cylinder imbedded in a magnetoionic medium under assumptions that the medium is lossless and the field frequency is not equal to the cyclotron frequency. It is shown that they are classified into two kinds: (i) k1 and k2 are pure imaginary and (ii) k22 = (complex conjugate of k12), where k1 and k2 are the radial propagation constants and that no eigenvalues exist in the region bounded by [Formula: see text] where ωp and ωc are the plasma and cyclotron frequencies normalized to the field frequency. Some numerical results in the case of (radius of the cylinder/wavelength) [Formula: see text] are also shown.
