The Development of Frequency Multipliers for Terahertz Remote Sensing System

This paper summarizes the development of novel Schottky-diode-based terahertz frequency multipliers. The basic structure and manufacturing process planar Schottky barrier diodes (SBDs) are reviewed, along with other diode structures that have been proposed in literature. A numerical modeling method for context multipliers is presented, which includes 3D electromagnetic (EM) modeling, electro-thermal physical non-ideal effects. Furthermore, a general design methodology developing introduced, involving sub-division (SDM), global (GDM) half-sub-division half-global (HS-HGDM). These methods summarized compared 110 GHz 220 communication imaging applications. Laboratory measurements these show good agreement simulations. Finally, several classic remote sensing systems system established using security inspection purposes presented associated results.
