Researchers from Shanghai Institute of Technical Physics and University of New South Wales developed a high performance multifunctional meta-photonic device with the capability of polarization-dispersion modulation for mid-wave infrared polarization detection.
A team led by Prof. QI Feng at the Terahertz Imaging Laboratory, Shenyang Institute of Automation, the Chinese Academy of Sciences demonstrated a fast and reliable time-domain method for removing FP effect in material characterization with THz-TDS. The study was published in the latest issue of IEEE Transactions on Terahertz Science and Technology.
Researchers from the Institute of Acoustics proposed that model-free parameters (P, Q) could describe the reflection characteristics of the sea bottom. They also demonstrated that the values of P and Q were consistent with the GA parameter values inverted from different models.
Researchers from the Institute of Acoustics achieved diffraction control in a non-Hermitian acoustic grating. They introduced periodic loss into the acoustic grating and utilized the combined modulation effect of the real refractive index and loss on the diffraction.
Researchers from the Institute of Acoustics extracted an accurate reflection coefficient to optimize the Pt/LGS device by using the short pulse method. The research shows that surface acoustic wave high temperature sensing technology could provide a good solution for high sensitive temperature monitoring and early warning in extremely high-temperature environment.
Researchers from the Institute of Acoustics proposed a type of supervised speech enhancement approach with residual noise control for voice communication. This approach could improve the quality of voice communication.
