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.
