This paper presents the design, fabrication, and characterization of the first millimeter-wave Graphene-based varactor on flexible substrates. The varactor achieves quality factor better than 10 up to 25 GHz with variation of 5–10% for a bending radius down to 5 mm with pronounced varactor behavior measured up to at least 70 GHz. To prove the substrate independence of the proposed varactor, we fabricated...
This work has developed a three-leaf trefoil-type corner cube retro-reflector (CCR) fabricated with the MUMPs polysilicon surface micromachining process. Unlike other MEMS CCRs, this CCR's opening faces straight upward as its (1, 1, 1) direction, i.e., the direction along which the retro-reflection efficiency is maximum, is perpendicular to the substrate's surface. Simulation results show that the...
The results of investigations of new compositions of electrically conductive adhesives (ECA) for printed electronics applications with and without nano-additives are presented. The studies covered the influence of nano additives on mechanical properties and reliability of interconnects made by elaborated, improved composition of the ECA based on primary conclusions. The obtained results showed that...

Robust and reliable interconnect and effective heat management are two major concerns in the high-speed and highpower integrated circuit. Carbon nanotube (CNT) exhibits amazing mechanical, thermal and electronic properties due to the unique structure. Those superior features make CNTs preferable and promising for application in electronic components and devices. In the present paper, carbon nanotube...
