Metamaterials and Metasurfaces for Sensor Applications
Electromagnetic metamaterials (MMs) and metasurfaces (MSs) are artificial media and surfaces with subwavelength separations of meta-atoms designed for anomalous manipulations of light properties. Owing to large scattering cross-sections of metallic/dielectric meta-atoms, it is possible to not only localize strong electromagnetic fields in deep subwavelength volume but also decompose and analyze...
متن کاملBabinet principle applied to the design of metasurfaces and metamaterials.
The electromagnetic theory of diffraction and the Babinet principle are applied to the design of artificial metasurfaces and metamaterials. A new particle, the complementary split rings resonator, is proposed for the design of metasurfaces with high frequency selectivity and planar metamaterials with a negative dielectric permittivity. Applications in the fields of frequency selective surfaces ...
متن کاملA Fractal-ANN approach for quality control
The main problem with modern quality control of sound speakers is that the process is conducted manually. This manual checking of the quality of sound speakers is time consuming. In order to find an automated way of doing this, this paper presents an intelligent system for automated quality control in sound speaker manufacturing, which fuses Fractal Dimension (FD) into Artificial Neural Network...
متن کاملFractal plasmonic metamaterials for subwavelength imaging.
We show that a metallic plate with periodic fractal-shaped slits can be homogenized as a plasmonic metamaterial with plasmon frequency dictated by the fractal geometry. Owing to the all-dimensional subwavelength nature of the fractal pattern, our system supports both transverse-electric and transverse-magnetic surface plasmons. As a result, this structure can be employed to focus light sources ...
متن کاملFractal Audio Coding
We explore the performance of applying fractal coding on audio data. Some conventional fractal coding problems have been studied with audio data to provide an overview on this subject. A review of fractal coding is presented. We implement a fractal audio coding scheme to carry out the experiments. The performance of the scheme can be controlled by a number of different parameters, including map...
