Abstract

The device includes interdigitated magnetic finger electrodes separated by dielectric material. The electrodes are magnetically polarized when electrically biased. Multiple fingers are connected together two form two parallel electrodes of a magnetic capacitor (Mcap). The interdigitated fingers increase the surface area of the capacitor compared to a parallel plate configuration. The colossal magnetic capacitance effect is also utilized to increase the storage capacity of the device or to reduce the device volume.

Description

technical field [0001] The present invention relates to an electrical energy storage device, and more particularly to a parallel plate magnetic capacitor device. Background technique [0002] Generally speaking, the structure of a parallel plate capacitor is composed of two parallel metal plates and an insulating material in the middle. The calculation of the capacitance value can be expressed by formula (1), and the energy corresponding to the capacitance value can be expressed by formula (2): [0003] C = e 0 e k A r - - - ( 1 ) [0004] E=(1 / 2)CV 2 (2) [0005] Among them, C represents the capacitance value of the parallel plate capacitor, e 0 represents the dielectric constant in vacuum, e k...
