Abstract

Ferrites are distinct material for electromagnetic applications due to its unique spin precession. In this paper, Casimir pressure effect by deploying magnetically tunable surface plasmon quanta in stratified structure of using ferrite and metal wires is presented. Previously, oscillating surface plasmon quanta were successfully included to modify first reflection and first transmission characteristics. The oscillating surface plasmon quanta in the modified reflection in such a system, not only does resolve in a typical matter in metamaterial, but also provide new applications such as creating Casimir pressure effects through the metamaterial composite shown in this paper. The Casimir pressure flips from attractive state to repulsive state is referred to cause mechanism of radiation from surface plasmon quanta. Both Casimir force analysis and the measured data of radiations indicate us the system develops quantized states by electric flux induced by ferromagnetic resonance. Quantum analysis is used to understand the discrete radiations spectra for our experimental measurement. The discrete radiations are reproduced by using time dependent Schr\"odinger representation. As a result, we find the Josephson frequency and Josephson current representations at room temperature and we used them for extrapolating voltage induced in excited ferrites. Josephson frequency at X-band is able to differentiate micron volt differences and it allows us to report the data for voltage induced by ferromagnetic resonance in ferrite at room temperature. It is understood that the radiation intensity depends on density of final states and excitation probability when we come to think the energy matter. It seems possible to create as high as 20mW microwave power inside waveguide at X-band.
