Homogenization Techniques for Periodic Structures
Sebastien Guenneau, Richard Craster, Tryfon Antonakakis +2
In this chapter we describe a selection of mathematical techniques and results that suggest interesting links between the theory of gratings and the theory of homogenization, inclu…
Proximity Factors of Lattice Reduction-Aided Precoding for Multiantenna Broadcast
Shuiyin Liu, Cong Ling, Xiaofu Wu
Lattice precoding is an effective strategy for multiantenna broadcast. In this paper, we show that approximate lattice precoding in multiantenna broadcast is a variant of the close…
Non-adiabatic electron behaviour due to short-scale electric field structures at collisionless shock waves
V. See, R. F. Cameron, S. J. Schwartz
Under sufficiently high electric field gradients, electron behaviour within exactly perpendicular shocks is unstable to the so-called trajectory instability. We extend previous wor…
A Dust-Obscured Massive Maximum-Starburst Galaxy at a Redshift of 6.34
Dominik A. Riechers, C. M. Bradford, D. L. Clements +61
Massive present-day early-type (elliptical and lenticular) galaxies probably gained the bulk of their stellar mass and heavy elements through intense, dust-enshrouded starbursts -…
Imperfect and Unmatched CSIT is Still Useful for the Frequency Correlated MISO Broadcast Channel
Chenxi Hao, Bruno Clerckx
Since Maddah-Ali and Tse showed that the completely stale transmitter-side channel state information (CSIT) still benefits the Degrees of Freedom (DoF) of the Multiple-Input-Multip…
Ab initio calculations of the optical absorption spectra of C60-conjugated polymer hybrids
Laura E. Ratcliff, Peter D. Haynes
A recently developed linear-scaling density-functional theory (LS-DFT) formalism is used to calculate optical absorption spectra of hybrids of C60 and the conjugated polymers poly(…
