We investigate femtosecond laser trapping dynamics of two-photon absorbing hollow-core nanoparticles with different volume fractions and two-photon absorption (
We propose a photonic-assisted single system for measuring the frequency and phase noise of microwave signals in a large spectral range.Both the frequency and p
We demonstrate a tunable terahertz (THz) absorber based on an indium tin oxide (ITO) metamaterial.The upper ITO cross-shaped metasurface with different arm leng
