摘要: In this paper, we presented a novel shape for nano-aperture biomedical and spectroscopy application. addition, when the graphene coat layer is added to structure, are achieving reconfigurable particle with more transmittance impedance parameters can describe effect of layer. The prototype structure simulated FDTD method by CST microwave studio substrate, SiN refractive index 1.98 thickness 80nm selected. Palik model implemented gold 30nm, single selected 1nm thickness. antenna has dual band characteristic at 46 86THz sensing mid infrared improving in nano-particle. Here show that implementation useful making biosensor accuracy sensitivity. shows orthogonal made it solar cell application energy harvesting enhancement electrical field both X Y directions. Display Omitted article, report simple optical enhancement.We increased Q-factor nano antenna.We have various FOM chemical potentials.With two-difference bias two so factors design biosensor.
