Nonlinear waves in Newton's cradle and the discrete p-Schroedinger equation
, 2010 We study nonlinear waves in Newton's cradle, a classical mechanical system consisting of a chain of beads attached to linear pendula and interacting nonlinearly via Hertz's contact forces.

Digital phantoms generated by spectral and spatial light modulators [PDF]
Journal of Biomedical Optics, 2015 A hyperspectral image projector (HIP) based on liquid crystal on silicon spatial light modulators is explained and demonstrated to generate data cubes. The HIP-constructed data cubes are three-dimensional images of the spatial distribution of spectrally resolved abundances of intracellular light-absorbing oxyhemoglobin molecules in single erythrocytes.

Detect-and-forward relaying aided cooperative spatial modulation for wireless networks
, 2013 A novel detect-and-forward (DeF) relaying aided cooperative SM scheme is proposed, which is capable of striking a flexible tradeoff in terms of the achievable bit error ratio (BER), complexity and unequal error protection (UEP).

Multiple Beamforming with Perfect Coding
, 2012 Perfect Space-Time Block Codes (PSTBCs) achieve full diversity, full rate, nonvanishing constant minimum determinant, uniform average transmitted energy per antenna, and good shaping. However, the high decoding complexity is a critical issue for practice.

Chromaticity-Adaptive Generalized Spatial Modulation for MIMO VLC With Multi-Color LEDs
IEEE Photonics Journal, 2019 In this paper, we propose a chromaticity-adaptive generalized spatial modulation (CA-GSM) method for multiple-input multiple-output (MIMO) visible light communication (VLC) systems with quadrichromatic LEDs (QLEDs).

Electromagnetic wave propagation in spatially homogeneous yet smoothly time-varying dielectric media
, 2015 We explore the propagation and transformation of electromagnetic waves through spatially homogeneous yet smoothly time-dependent media within the framework of classical electrodynamics. By modelling the smooth transition, occurring during a finite period

Train of high-power femtosecond pulses: Probe wave in a gas of prepared atoms
, 2009 We present a new method for generating a regular train of ultrashort optical pulses in a prepared two-level medium. The train develops from incident monochromatic probe radiation travelling in a medium of atoms, which are in a quantum mechanical ...
