Figure 1: Spectral angular distribution of THz radiation (arb. units) in the (ky, kz) plane produced by Ex and Bx along the laser polarization axis in the following configurations: From: Terahertz radiation driven by two-color laser pulses at near-relativistic intensities: Competition between...
The dark blue region corresponds to the forbidden band, and the red dashed line indicates the frequency of 467 THz (\(\lambda \,\)= 643 nm), at which the transmissivity satisfied the function \(t={t}_{0}+{t}_{2}{k}_{r}^{2}\) as illustrated in Fig. S1b in the ...
However, when Lpr/Lre is too large, the receiving plane will be too small and a large number of high-frequency components will be lost in the reconstructed image, resulting in image blur. In this paper, the plus sign graphic simulation is used to obtain the optimal sampling plane, and ...
