Access provided by: anon Sign Out. The base of fractal antenna theory and applications: Utilizing in electronic devices Abstract: Computer simulation is employed to simulate the electrodynamic parameters of new fractal antennas and frequency-selective surfaces based on such antennas at the frequency range up to 20 GHz.
The analysis of the original fractal antennas is supplemented with the study of the fractal frequency-selective 3D media or fractal sandwiches i. The efficiency of the fractal antennas and the fractal frequency-selective 3D media is demonstrated. The methods to create new passive electron components and elements for modern broadband and multifrequency radio systems based on such media are proposed.
Article :. DOI: Abstract : The concept of fractal geometry, introduced by Mandelbrot has been explored in diverse areas of science, including acoustics .
First part of this work relates the properties of far-field Fraunhofer region diffraction in wave acoustics for characterizing reflection on a periodic regular indented plane. Diffusion prediction of a self-similar structure, the Sierpinski carpet, is then developed through the computation of its spatial Fourier transform.
Scattering intensity computation results show that after propagation of a coherent plane wave through the structure, the resulting acoustical field displays fractal properties itself, showing a self-similar structure of the reflected signal. This computational approach of the Sierpinski carpet's scattering properties will lead us to develop, in a near future, an acoustic angular scattering measurement process, applied to a Sierpinski tetrahedron 3-D scale model.
