Layer Stripping for the Helmholtz Equation

SIAM Journal on Applied Mathematics, 1996
Summary: We develop a new layer stripping technique for the inverse scattering problem for the one-dimensional Helmholtz equation on the half line. The technique eliminates the use of ``trace formulas'', relying instead on a nonlinear Plancherel equality that provides a simple and precise characterization of the reflection data.

METHOD FOR ADJUSTING A HELMHOLTZ RESONATOR AND AN ADJUSTABLE HELMHOLTZ RESONATOR

The Journal of the Acoustical Society of America, 2013
In a method for adjusting a Helmholtz resonator ( 10 ), in which a resonator volume ( 11 ) is connected to a space ( 13 ) to be provided with damping along an axis ( 29 ) via a constriction ( 12 ) having an acoustic impedance, the acoustic impedance of the constriction ( 12 ) is altered in order to adjust the Helmholtz resonator ( 10 ).

Polarimetric Helmholtz Stereopsis

IEEE Transactions on Pattern Analysis and Machine Intelligence
Helmholtz stereopsis (HS) exploits the reciprocity principle of light propagation (i.e., the Helmholtz reciprocity) for 3D reconstruction of surfaces with arbitrary reflectance. In this paper, we present the polarimetric Helmholtz stereopsis (polar-HS), which extends the classical HS by considering the polarization state of light in the reciprocal ...
