MATHEMATHICAL MODELLING OF METAMATERIALS AND ANALYSIS OF THEIR OPTICAL PROPERTIES - завантажити (стор. 112-118)
In this work were studied fishnet metamaterials with proposed meshy structure. The spectral bands with negative refractive index were discovered in near infrared and visible regions. The linear red shift of spectral features was observed with the increasing partition order of fractal. These optical features of discussed metamaterials could find possible applications in optical devices (filters, lenses, modulators etc.), high-sensitive pressure sensor meters and other devices.Obtained in math modeling linear dependences of the peak positions of negative refractive index (NRI) from geometric parameters of metamaterials can be used to adjust the spectral position of optical features in the production of meshy metamaterials with given functional characteristics. In the work were discussed prospects of use of the considered metamaterials in optical devices such as filters, lenses, modulators, etc., as well as highly sensitive pressure sensors, biological and chemical sensors with anti-interference remote control.
