Chains with Fractal Dispersion Law
نویسنده
چکیده
Chains with long-range interactions are considered. The interactions are defined such that each nth particle interacts only with chain particles with the numbers n±a(m), where m = 1, 2, 3, ... and a(m) is an integer-valued function. Exponential type functions a(m) = b, where b = 2, 3, .., are discussed. The correspondent pseudodifferential equations of chain oscillations are obtained. Dispersion laws of the suggested chains are described by the Weierstrass and Weierstrass-Mandelbrot functions. PACS: 05.45.Df; 45.05.+x; 45.50.-j

متن کاملDesign of low-dispersion fractal photonic crystal fiber
In this paper, a fractal photonic crystal fiber (F-PCF) based on the 1st iteration of Koch fractal configuration for optical communication systems is presented. Complex structure of fractal shape is build up through replication of a base shape. Nowadays, fractal shapes are used widely in antenna topics and its usage in PCF has not been investigated yet. The purpose of this research is to compar...
متن کاملOn The Behavior of Malaysian Equities: Fractal Analysis Approach
Fractal analyzing of continuous processes have recently emerged in literatures in various domains. Existence of long memory in many processes including financial time series have been evidenced via different methodologies in many literatures in past decade, which has inspired many recent literatures on quantifying the fractional Brownian motion (fBm) characteristics of financial time series. Th...
متن کاملApplication of Power-Law Frequency Fractal Model for Recognition of Vertical Cu Distribution in Milloieh Porphyry Deposit, SE Iran
Identification of the vertical and horizontal distributions for elemental grades is of an important sign in different mineral exploration stages. The main aim of this work is to determine the vertical distribution directional properties of Cu values in the Milloieh Cu porphyry deposit, Kerman (SE Iran) using the power-law frequency fractal model. This work is carried out based on four mineraliz...
متن کاملFractal Properties of Periodic Plasma Waveguides
Recently great interest is attracted by the problems concerning investigation of electromagnetic properties of periodic vacuum systems with plasma filling, so called hybrid structures [1, 2]. This interest is caused mostly by the possibility of creating of new powerful generators and accelerators due to the amplitude increasing comparatively to those ones but with vacuum filling. Interesting an...
