## Abstract The work of Barba et al.1 is fatally flawed on two counts: (i) the existence of Tellegen mediums is unrecognizable in modern electromagnetic theory, and (ii) the timeβdomain constitutive relations used in the commented upon work are noncausal.

## Communicated by Y. Shibata We consider the self-adjoint operator governing the propagation of elastic waves in perturbed stratified media R3 with free boundary-interface conditions. In this paper we establish the limiting absorption principle for this self-adjoint operator in appropriate Hilber
## Abstract Cabeceira et al. recently presented a timeβdomain analysis of wave propagation in a Tellegen medium [1]. Their analysis is illβfounded because (i) the existence of any Tellegen medium is not tenable within modern electromagnetic theory; and (ii) the constitutive relations employed are n
dedicated to professor kyu ya masuda on the occasion of his 60th birthday The inverse scattering problem for the wave equation 2 t u=c(x, y) 2 2 x, y u is considered in R n x \_R 1 y , n 2. The sound speed of the background medium, c 0 ( y), takes different constant values on [ y>0] and [ y<0]. Th
