Popis: | This paper presents theoretical analysis on fundamental performances of two configurations of magnetoelectric transducers that are used the most in practice, longitudinal-longitudinal and longitudinal-transverse modes, with a focus on magnetic field sensing and wireless power transfer applications. Based on equivalent circuit models and two-port network theory, we derive explicit closed-form solutions for the magnetoelecitric voltage coefficient and the power delivered to a load. We reveal that although the former configuration exhibits some advantages of utilizing as a sensing system, there is no difference in the maximum output power obtained from the two methods. The question on how to reach the upper bound on transferred power is also discussed. The findings can be used as a generalized framework to design an optimal system, depending on desired applications. |
