Supplementary Figure S1: Antenna enhancement for another antenna-particle pair: Same graph as in Fig.4 of the main text, but for another antenna-nanoparticle pair. The black curve shows the differential pump-probe spectrum of a single nanoparticle with 50 nm in diameter. As predicted this signal is stronger and also red shifted by about ∆λ = 20 nm compared to the single 40 nm nanoparticle shown...
To determine whether particular sources of gravitational radiation will be detectable by a specific gravitational wave detector, it is necessary to know the sensitivity limits of the instrument. These instrumental sensitivities are often depicted ~after averaging over source position and polarization! by graphing the minimal values of the gravitational wave amplitude detectable by the instrumen...
Multiferroic BaMnF4 powder was prepared by hydrothermal method. Hysteretic field dependent magnetization curve at 5 K confirms the weak ferromagnetism aroused from the canted antiferromagnetic spins by magnetoelectric coupling. The blocking temperature of 65 K for exchange bias coincides well with the peak at 65 K in the zero-field cooled temperature-dependent magnetization curve, which has bee...
A fiber-optic current sensor based on the Faraday Effect is developed for aircraft installations. It can measure total lightning current amplitudes and waveforms, including continuing current. Additional benefits include being small, lightweight, non-conducting, safe from electromagnetic interference, and free of hysteresis and saturation. The Faraday Effect causes light polarization to rotate ...
Abstract This paper presents a test method of satellite communication based on dual circular polarization diversity. A polarized channel model is established two validated models to obtain the bit error rate curve MIMO system. Moreover, specific antennas are chosen through simulation result cross-polar discrimination (XPD). Finally, hardware platform with USRPE310 and polarized-antenna verify r...
The remaining useful lifetime (RUL) of proton exchange membrane fuel cell (PEMFC) has been influenced by the heterogeneous distribution. In this presented paper, a novel method considering internal heterogeneity is proposed and investigated to manage operation thus prolonging lifetime. This including mathematic steps quantification, normalization, coordinate transformation, converts conventiona...
The exciting detection of a very high degree of linear polarization, P = 80%±20%, in the prompt γ-ray emission of the recent GRB 021206, provides strong evidence that synchrotron emission is the dominant radiation mechanism. Besides this immediate implication, there were also claims that this implies a magnetic field that is ordered on large scales within the ejecta, and must therefore be produ...
We have simultaneously modeled both the interstellar extinction and polarization (both linear and circular) on the basis of a trimodal dust model: large silicate core-organic refractory mantle dust particles; very small carbonaceous particles responsible for the hump extinction; and PAH’s responsible for the FUV extinction. The core-mantle particles which are the exclusive contributor to the in...
This study demonstrates for the first time abnormal electro-optic (EO) characteristics induced by electrohydrodynamics (EHD) in a polymer-dispersed liquid crystal (PDLC) film in the presence of a low-frequency (1 kHz) AC voltage. Large LC droplets (20−40 μm) buried in the film can be obtained after the illumination of one UV light with a weak intensity (~0.96 mW/cm2) for 12 h. This film exhibit...
Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
