ABSTRACT
High performance THz imaging systems can be constructed by the proposed on-chip metamaterial-based signal sources, receivers and antennas in the previous sections. As illustrated in Figure 12.1, A high power THz signal firstly generated by MPW-based zero-phase CON and then radiated by the CRLH T-line-based on-chip LWA. After penetrating through the sample under test, the resulting THz signal is received by a high sensitivity super-regenerative receivers by TL-SRR/TL-CSRR-based quench-controlled oscillators. With the proposed transmitter and receiver designs, both narrow-band and wide-band THz imaging systems can be demonstrated at 135 GHz and 280 GHz, respectively.
