Terahertz Spatiotemporal Wave Synthesis in Random Systems
Complex media have emerged as a powerful and robust framework
to
control light–matter interactions designed for task-specific
optical functionalities. Studies on wavefront shaping through disordered
systems have demonstrated optical wave manipulation capabilities beyond
conventional optics, including aberration-free and subwavelength focusing.
However, achieving arbitrary and simultaneous control over the spatial
and temporal features of light remains challenging. In particular,
no practical solution exists for field-level arbitrary spatiotemporal
control of wave packets. A new paradigm shift has emerged in the terahertz
frequency domain, offering methods for absolute time-domain measurements
of the scattered electric field, enabling direct field-based wave
synthesis. In this work, we report the experimental demonstration
of field-level control of single-cycle terahertz pulses on arbitrary
spatial points through complex disordered media
