Abstract
In this paper, the development of a high performance nano-sized micro/nano scale device called a Panda ring resonator is presented for brain investigation. It is a nonlinear optical/spintronic device, which can be used under the concept of nonlinear Panda ring resonator for various applications. The ideal operation of the Panda ring resonator will be realized by using the spin-wave packet confined in the coupled ferromagnetic circular nanorings, where the field sensing with nano-meter spatial resolution and ultra-high sensitivity comparable to the fabricated device, which will be demonstrated at room temperature with keeping high tenability and flexibility. In practice, such a device can be designed and worked similarly for various optical applications, where in this case the metallic device will be used instead of optical device (semiconductor). Moreover, this is a spin-wave electronic device, in which the current free device concept is introduced, which is useful for brain investigation, in which non-invasive investigation is realized. By extending these sensing techniques, we will also develop the novel high performance spintronic devices such as nano-medical detector and brain sensors, which are theoretically confirmed by the author’s previous works. These innovative demonstrations make a breakthrough for spin-based nano-electronic and energy harvesting devices. Finally, the spin wave device design, fabrication and taste for various applications will be discussed.
