Harmonic Analysis of Periodic Vectors and Functions Periodic at Infinity
Journal of Mathematical Sciences, 2015Summary: We study vector-valued slowly varying and periodic at infinity functions of several variables. We prove a counterpart of the Wiener theorem on absolutely converging Fourier series. We establish a criterion for representation of periodic at infinity functions as the sum of periodic functions and functions converging to zero and a criterion of ...

Analysis of periodical dielectric waveguide with two grating periods
2012 IEEE 3rd International Conference on Photonics, 2012In the paper, the periodical dielectric waveguide with two grating periods is demonstrated. We used the Floquet-Bloch theory to analyze the transmission and reflection spectra.

Stability analysis of nonlinear periodic media
Physical Review A, 1992While the analysis of the stationary solutions of nonlinear periodic media suggests the existence of gap-soliton-induced bistability, numerical simulations show that some of the states involved are unstable. To investigate the instability, a linear stability analysis is presented showing the stable and unstable regions as a function of both the ...

Period Analysis Based on CNN and Periodicity Ratio Method
Volume 8: Dynamic Systems and Control, Parts A and B, 2010In this work, we use a new approach to test whether the data from a numerical solution of a nonlinear differential system are periodic. If so, we can further check the corresponding period. A cellular neural/nonlinear network (CNN) has been used to test the data from the phase trajectory of the system.

Analysis of periodic structures
2016Many electromagnetic applications require the use of periodic structures such as frequency selective surfaces (FSS), electromagnetic band gap structures, corrugated surfaces, phased antenna arrays, periodic absorbers or negative index materials. These structures extend to several wavelengths in size therefore their analyses are time-consuming and ...

Footprint Analysis During the Growth Period
Journal of Pediatric Orthopaedics, 1994Static footprints were obtained from 672 healthy white subjects ranging in age from newborn to 15 years. The length of the footprint was measured and the medial longitudinal arch was evaluated. The findings showed that the feet grew most rapidly up to 3 years of age.
