Figure 2

Time-domain characterization of the transient wire-grid polarizer. (a) Transient electric field of a THz pulse that has traversed an Si slab without excitation. (b) 60 ps after homogeneous excitation with an 800 nm pump pulse. (c) 60 ps after excitation with the pattern of Figure 1b with the THz polarization parallel. (d) Perpendicular to the wire orientation. The different amplitude and phase shift of the waveforms in c and d are a clear signature of the highly anisotropic response of the transient metamaterial. THz, terahertz.
