Abstract:

The report describes transmission system and network analogies to geophysical forward and inverse problems. Applications to one, two and three dimensional problems are discussed. The use of network theorems in developing reciprocity and sensitivity relationships that simplify the calculations for solving the inverse boundary value problem are discussed. Author
