    New exact solutions for the three-dimensional Electrical Impedance Equation applying quaternionic analysis and pseudoanalytic function theory
    (2009) Marco Pedro Ramírez Tachiquín; O. Rodriguez Torres; J. J. Gutierrez Cortes
    We introduce a set of linearly independent solutions for the three-dimensional quaternionic electrical impedance equation, when the conductivity is a two-dimensional separable-variables function, and using a generalization of the Beltrami equation, we study two particular cases when the electrical impedance equation turns into a p-analytic system. Then we express analytically its general solution in terms of Taylor series in formal powers. This allows us to introduce a new class of exact solutions for the three-dimensional electrical impedance equation.

    On a wireless power transmission system for an implantable prosthesis telemetry unit
    (2009) A.H. Lecona; J. J. Gutierrez Cortes; O. Rodriguez Torres; Marco Pedro Ramírez Tachiquín; Víctor Manuel Domínguez‐Hernández; Víctor Manuel Araujo Monsalvo
    We propose a wireless electrical power transmission system, for energizing a stress monitoring arrangement on the surface of a Titanium based-alloy prosthesis implant. Applying standard methods for characterizing cylindric coils, we find a frequency range that warrants the maximum power transmission, and we propose an electronic circuit for transmitting the sensed values by virtue of radio waves. We also mention some unexpected phenomena of power transference at very low frequencies.
