Stable rational approximations for parabolic equation methods
Adith Ramamurti, Joseph F. Lingevitch, Jonathan C. Lighthall +1
Modern parabolic equation (PE) methods for wave propagation rely on application of a variety of fractional-powered differential operators. Rational approximations of these operator…
Approaches for handling sloping fluid-solid interfaces with the parabolic equation method
Michael D. Collins, Adith Ramamurti
Several methods for handling sloping fluid-solid interfaces with the elastic parabolic equation are tested. A single-scattering approach that is modified for the fluid-solid case i…
Impulsive Noise Immunity of Multidimensional Pulse Position Modulation
Michael D. Collins, William B. Johnson
We describe block oriented multidimensional pulse position modulation and its resilience against impulsive noise. The modulation implements the encoder and part of the decoder of t…
