Description
technical field [0001] The invention relates to a terahertz wave beam splitter, in particular to a terahertz wave polarization beam splitter with a silicon array structure. Background technique [0002] In recent years, the terahertz wave between the mature millimeter wave and infrared light on the electromagnetic spectrum is undoubtedly a new research field. The frequency of terahertz wave is 0.1-10THz, and the wavelength is 30μm-3mm. For a long time, due to the lack of effective terahertz wave generation and detection methods, compared with traditional microwave technology and optical technology, people have little understanding of the nature of electromagnetic radiation in this band, so that this band has become the terahertz wave in the electromagnetic spectrum. void. With the breakthrough of terahertz radiation source and detection technology, the unique and superior characteristics of terahertz have been discovered and have shown great application prospects in materi...
