Claim One:
1. A method for determining a plurality of parameters of interest of an anisotropic formation comprising: (a) conveying an electromagnetic wave propagation device in a borehole in the anisotropic formation, said device having a plurality of spaced apart receivers and transmitters; (b) inducing electromagnetic radiation in the formation by energizing at least one transmitter; (c) defining at least two parameters of interest to be determined, one of said parameters of interest to be determined being the horizontal wave number of the induced electromagnetic radiation; (d) obtaining at least three predefined measurements at said plurality of receivers; (e) defining a model that relates the at least three measurements to the at least two parameters of interest to be determined; (f) determining ambiguous values of the at least two parameters of interest by utilizing the at least three measurements and the model; and (g) determining an unambiguous value of the at least two parameters of interest from said ambiguous values.
