Microwave magnetoelectric particles: an experimental study of oscillating spectrums.

One of the ways to uncover the nature of the microwave magnetoelectric (ME) effect, recently observed in small ferrite resonators with special-form surface metallizations, is a comparative analysis of oscillating spectrums excited by different type rf external fields. Experimental results of the ME coupling in different types of ferrite resonators and different types of surface electrodes are reported and some important conclusions are drawn observing the oscillating spectrums of those particles. A special interest in spectral properties of point ME particles should be found in the field of microwave artificial composite materials-bianisotropic materials.
