AVO modeling for P and S-waves (including P-P, P-SV, SV-SV, SV-P and S-SH waves) of two-dimensional undulate layered model was made by using fast ray-tracing algorithm as well as formulas for calculating reflection and transmission coefficients of plane wave traveling at reflection interface.
The generalized spectral domain-exponential matrix technique is used to study the reflection and transmission properties of multilayered uniaxial chiral composites which possess bi-chirality structures. Numerical results are presented to demonstrate the influences of the orientation axis,lossness, chirality and non-reciprocity parameters on the reflection and transmission coefficients. Especially ,the effect of cross-polarized transformation is considered.
A definition of reflection and transmission coefficient of sound wave is given, and the relationship between them and the quality of medium is discussed, together with the regularity of the angle of incidence.
Multiwave amplitude characteristic equation has been deduced based on the method of Aki and Richards in the paper. The multiwave reflection and transmission coefficient of plane waves in TI media can be precisely computed and the parameters of a stratum can be inverted by the equation.
Analytic formulas for the reflection and transmission coefficients and their shortwave and longwave asymptotics are obtained.
Numerical calculations are performed and the plots are presented for the frequency dependences of the reflection and transmission coefficients for various parameters of the constituting lines.
Errors in determination of the complex reflection and transmission coefficients of sound for samples tested are calculated theoretically.
For samples of screens made in the form of a steel layer with an overlying stack of rubber layers with cylindrical voids, the reflection and transmission coefficients are measured using the Low-Frequency Acoustic Pipe system.
The statistics of the reflection and transmission coefficients for the incident and excited waves are discussed.
