Broadband mode conversion via gradient index metamaterials
HaiXiao Wang, YaDong Xu, Patrice Genevet +2
We propose a design for broadband waveguide mode conversion based on gradient index metamaterials (GIMs). Numerical simulations demonstrate that the zeroth order of transverse magn…
Conjugate metamaterials and the perfect lens
Yadong Xu, Yangyang Fu, Lin Xu +1
In this letter, we show how transformation optics makes it possible to design what we call conjugate metamaterials. We show that these materials can also serve as substrates for ma…
Coexistence of Scattering Enhancement and Suppression by Plasmonic Cavity Modes in Loaded Dimer Gap-Antennas
Qiang Zhang, Jun-Jun Xiao, Meili Li +2
Plasmonic nanoantenna is of promising applications in optical sensing, single-molecular detection, and enhancement of optical nonlinear effect, surface optical spectroscopy, photoc…
Invisible sensor: Simultaneous sensing and camouflaging in multiphysical fields
Tian-Zhi Yang, Xue Bai, Dongliang Gao +4
To manipulate various types of physical signals in one single device has long captivated the attention of scientists and engineers. This however is very challenging, if not impossi…
