Dynamic indoor free-space optical communication enabled by beam steering and beam shaping

Autor: Spencer Liverman, Cade W. Trotter, Luc Bouchard, Hayden Bialek, Thinh Nguyen, Arun Natarajan, Alan X. Wang

Publikováno v: Applied Optics. 62:2367

Indoor free-space optical communication (FSO) provides orders of magnitude larger usable bandwidth compared to radio-frequency links but suffers from an intrinsic trade-off between areal coverage and received power. In this paper, we report a dynamic

A Noise-Cancelling Self-Interference Canceller with +7 dBm Self-Interference Power Handling in 0.18μ m CMOS

Autor: Amin Aghighi, Harish Krishnaswamy, Arun Natarajan, Hayden Bialek, Mostafa Essawy, Aravind Nagulu

Publikováno v: 2021 IEEE Radio Frequency Integrated Circuits Symposium (RFIC).

Self-interference (SI) mitigation is critical for full-duplex and frequency-domain duplex systems. Canceller noise and linearity limits the SI power that can be tolerated at RX input. A dual-path SI cancellation scheme is presented where the noise an

Bi-directional channel modeling for implantable UHF–RFID transceivers in brain–computer interface applications

Autor: Hayden Bialek, Syed Hassan Ahmed, Mahasweta Sarkar, Shams Al Ajrawi, Ramesh R. Rao

Publikováno v: Future Generation Computer Systems. 88:683-692

Bi-directional Brain–Computer Interfacing (BBCI) faces major challenges due to, in part, the difficulty of transmission of Electro-corticographical (ECoG) signals from the brain to external devices. For human subjects, safety and convenience would

Portable real-time PCR system using tablet-based fluorescence imaging

Autor: Donald Heer, Jacob Dawes, Hayden Bialek, Matthew L. Johnston

Publikováno v: 2016 IEEE EMBS International Student Conference (ISC).

The quantitative polymerase chain reaction (qPCR) is a key medical tool for diagnosing and monitoring viral infections. Due to the high cost and large size of existing qPCR machines, it is rarely viable for remote and resource-limited areas. A portab
