Modelling of Transmission Lines Based on Power Waves and Transfer Coefficients
2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020Transmission line model (TLM) has been widely used in various transmission systems. The traditional TLM takes voltages and currents as unknowns in modelling. In this paper, another modeling idea is proposed, which is named power wave-based transmission line modeling (PW-TLM) and takes power waves as unknowns.

Phase of the transmission coefficient of waves in one-dimensional random media
Journal of the Korean Physical Society, 2012We study the behavior of the phase of the transmission coefficient t in random media by using the invariant imbedding method of wave propagation. We calculate the disorder average of t/t* for waves propagating in one-dimensional random media with uncorrelated Gaussian disorder in a numerically exact manner.

Reflection and Transmission Coefficients of Plane Waves in Magnetoelectroelastic Layered Structures
Journal of Vibration and Acoustics, 2008Reflection and transmission coefficients of plane waves with oblique incidence to a multilayered system of piezomagnetic and/or piezoelectric materials are investigated in this paper. The general Christoffel equation is derived from the coupled constitutive and balance equations, which is further employed to solve the elastic displacements and electric

Estimation of Wave Transmission Coefficients for Permeable Breakwaters
2023The Madsen and White (1976) analytical model of wave transmission through permeable breakwaters is combined with a wave transmission by overtopping formula to provide a method of predicting wave transmission coefficients for permeable breakwaters. Comparison of this combined prediction technique with physical model laboratory tests shows that the ...

Determination of Wave Transmission Coefficients for Oyster Shell Bag Breakwaters
Coastal Engineering Practice (2011), 2011Problems are inevitable in the use of oyster shell bag breakwaters. Oyster shell bag breakwaters have been used in many locations throughout the USA to quantify their ecological benefits, but little research has been conducted regarding their wave attenuating properties. Quantitative information has been produced for traditional structures, but nothing

REFLECTION AND TRANSMISSION COEFFICIENTS FOR PLANE LONGITUDINAL INCIDENT WAVES
Geophysical Prospecting, 1962AbstractTables are presented giving the two reflection coefficients and the two transmission coefficients resulting from the incidence of a plane longitudinal wave upon a plane boundary between two elastic media, for hundred different combinations of the elastic parameters and the density of the two media. The effect of these parameters upon the change

Measurements of reflection and transmission coefficients of Rayleigh waves from cracks
The Journal of the Acoustical Society of America, 1984The angle and frequency dependence of reflection and transmission coefficients of Rayleigh waves from surface cracks in titanium has been measured. The measured results are compared to the recently developed theory of Angel and Achenbach [J. Acoust. Soc. Am. 75, 313–319 (1984)]. Very good agreement is obtained between experiment and theory.

Reflection and transmission coefficients for seismic waves in ellipsoidally anistropic media
Geophysics, 1979Abstract The deficiency of an isotropic model of the earth in the explanation of observed traveltime phenomena has led to the mathematical investigation of elastic wave propagation in anisotropic media. A type of anisotropy dealt with in the literature (Potsma, 1955; Cerveny and Psencik, 1972; and Vlaar, 1968) is uniaxial anisotropy ...

A gradient dielectric layer is considered. In the layer, permittivity ɛ(z) depends on coordinate z as follows: ɛ(z) = ɛL a 4/(z − a)4 (a being the gradientness parameter). For this layer, reflection and transmission coefficients r r and r t are determined.
