Basic Studies in Microwave Sciences
Abstract
This project studies (i) DI water properties under high-electric field stress, and (ii) CMOS circuits to capture and analyze short electrical pulses. For the first task, microwave microfluidic channels are fabricated with 260 nm channel heights. DC voltages up to 38 V are applied to DI water with its dielectric permittivity measured up to 16 GHz. Significant water permittivity reduction is observed when the applied field is ~1 MV/cm. A new technique is proposed and demonstrated for sub-10 nm planar nanofluidic channel fabrication. For the second task, a CMOS transmission line based pulse capture and analysis circuit is proposed and analyzed. CMOS meander lines, which are used for spatial signal sampling, are tested and modeled. CMOS transmission-line based pulse generators are also studied and tested. This project supported 1 Ph. D. student, who are scheduled to graduate next year, and 1 MS student, who are scheduled to graduate in December. From the work in this project, 3 peer-reviewed journal papers have been published with 2 journal submissions under revision and 1 journal submissions under preparation. This work also produced two peer-reviewed conference publications with two abstracts accepted for presentations. Additionally, two provisional patent applications have been filed. Due to the results from the planar nanofluidic channel work in this project, NSF is currently supporting further research in this direction.
