Abstract

Stoneley waves exist on the boundaries between a limited range of isotropic and anisotropic solids and have been directly and indirectly detected on several pairs at ultrasonic frequencies [D. A. Lee and D. M. Corbly, IEEE Trans. Sonics Ultrason. SU-24, 206 (1977); R. O. Claus and C. H. Palmer, Appl. Phys. Lett. 31, 547 (1977)]. Of particular importance to current optical measurements are those waves that exist between pairs of transparent glass substrates for which Weichert's condition, μ1/μ2 ≈ ρ1/ρ2 ≈ 1, is nearly satisfied. We study the range of possible existence for these pairs and indicate that the existence region in the (μ1/μ2), (ρ1/ρ2) plane defined by Scholte [Proc. Ned. Akad. Weten. 45, 20, 159, 380, 439, 516, (1942)] degenerates to a single point when the media obey Weichert's equality. Experimental implication of the theoretical results is discussed.
