A Transmission Model of Analog Signals in Photonic Links
IEEE Photonics Journal, 2014 We investigate the transmission of analog photonic signals based on coupled-mode theory and small-signal analysis and provide general expressions for signal evolution along standard single-mode-fiber links.

Direct electrocaloric measurement of 0.9Pb(Mg
, 2016 We show that scanning thermal microscopy can measure reversible electrocaloric (EC) effects in <40 μm-thick ceramic films of the relaxor ferroelectric 0.9Pb(Mg1/3Nb2/3)O3-0.1PbTiO3, with the substrate present.

Analysis and Design of Channel Estimation in Multicell Multiuser MIMO OFDM Systems [PDF]
, 2015 This paper investigates the uplink transmission in multicell multiuser multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. The system model considers imperfect channel estimation, pilot contamination (PC), and
