IT has been well established 1,2 that, in the case of diffraction of light by very-high-frequency sound waves only the first order of diffraction appears in the field of view and it attains the ...
SIAM Journal on Applied Mathematics, Vol. 59, No. 3 (Dec., 1998 - Mar., 1999), pp. 1028-1052 (25 pages) We discuss in this paper a generalized impedance boundary condition that can be used locally to ...
We use in this paper a generalized impedance boundary condition equivalent to a thin layer of material with dielectric absorbing constants to compute in the high frequency regime the trace of the ...
