Wave transmission through a one-dimensional fractal system

Transmission properties of one dimensional fractal structures

In this paper, the optical properties of one dimensional fractal structures are investigated. We consider six typical fractal photonic structures: the symmetric dual cantor-like fractal structure, the asymmetric dual cantor-like fractal structure, the single cantor-like fractal structure, the symmetric dual golden-section fractal structure, the asymmetric dual golden-section fractal structure a...

Coherent transmission through a one dimensional quantum dot linear array

Based on the Keldysh nonequilibrium Green function (NGF) technique, a general formula for the current and transmission coefficient through a one dimensional quantum dot lattice is derived without the consideration of electron-electron interactions. We obtain an analytical condition for complete resonant transmission when the levels of dots are aligned, which depends on the parity of the number ...

Experimental Studies of Wave Transmission through Single Perforated Sheets and Upright Perforated Wave Filters

A one-dimensional model for variations of longitudinal wave velocity under different thermal conditions

Ultrasonic testing is a versatile and important nondestructive testing method. In many industrial applications, ultrasonic testing is carried out at relatively high temperatures. Since the ultrasonic w...

Solitary Wave in One-dimensional Buckyball System at Nanoscale

We have studied the stress wave propagation in one-dimensional (1-D) nanoscopic buckyball (C60) system by molecular dynamics (MD) simulation and quantitative modeling. Simulation results have shown that solitary waves are generated and propagating in the buckyball system through impacting one buckyball at one end of the buckyball chain. We have found the solitary wave behaviors are closely depe...
