A dynamically reconfigurable terahertz array antenna for 2D-imaging applications

An array of dipole antenna for multichannel near field imaging has been designed, fabricated and characterized using Terahertz time domain spectroscopy (THz-TDS) system. A 2D Terahertz image using the designed antenna can be obtained by reconfiguring the wavefront of the optical probe beam using the spatial light modulator. As a proof of concept, the THz spectrum of one of the dipole antenna is measured and presented.
