In the different phases of prospective campaigns for metallic minerals such as copper, Geophysics acts as a support tool both in the recognition of new exploratory targets and the expansion of known deposits, due to the ...
Modelling electromagnetic responses of 2-D structures due to spatially non-uniform inducing fields. Analysis of magnetotelluric source effects at coastlines
(Wiley Blackwell Publishing, Inc, 2003-10)
In previous works, we presented 2-D and 3-D magnetotelluric modelling methods based on Rayleigh-Fourier expansions. These methods are an alternative to finite-element and finite-difference techniques and are especially ...
