Goals The theory of sound and electromagnetic wave propagation is the basis of seismic methods, seismology and electromagnetics methods related to geophysical engineering. The aim of the course is to train the students who have the theoretical knowledge about the aim wave propagation and can follow the theoretical developments.
Course Content Principle of Elastisity: Displacement vector, stress, strain, stress-strain relation and elastic wave equation Representation Theorem: Plane waves, Green theory, total wave field, scattered wave field. Kirchhoff and Born Approximations of the Elastic waves: Green’s tensor in homogeneous infinite and half space isotropic mediums, Green’s tensor for surface waves. Electromagnetic Waves: Maxwell equations and Helmholtz wave equations, propagation constant, attenuation constant and phase constant. Electromagnetic Plane Waves: Uniform plane wave (transverse electromagnetic wave), wave characteristics in lossy and lossless media. Intrinsic impedance, skin effect. Plane Wave Reflection/Transmission: Parallel polarization, perpendicular polarization. Integral Forms of the Maxwell Equation: Green’s tensor in homogeneous infinite and half space isotropic medium.
Learning Outcomes 1) Define Sound and EM Waves according to their publishing principles, obtain wave equation, reveal their solutions.
2) Students learn the methods which have an important place in wave propagation theory and have knowledge to follow theoretical developments.
3) Students learn the methods which have an important place in wave propagation theory and have knowledge to follow theoretical developments.
4) They are sensitive modeling the ways of the rays by determining the tensor of the propagation and creating the ground model; reflection, refraction and scattering principles of waves according to wave types and in-situ parameters,
5) By using their knowledge they can work on putting the ground parameters by combining the wave field modeling and inverse methods.
6) Science or technology develops a new scientific method or technological product / process that brings innovation or makes a comprehensive research that applies a known method to a new field.
