terahertz biotechnology has been increasingly applied in various biomedical fields and has especially shown great potential for application in brain sciences.In this article,we review the development of terahertz biotechnology and its applications in the field of neuropsychiatry.Available evidence indicates promising prospects for the use of terahertz spectroscopy and terahertz imaging techniques in the diagnosis of amyloid disease,cerebrovascular disease,glioma,psychiatric disease,traumatic brain injury,and myelin deficit.In vitro and animal experiments have also demonstrated the potential therapeutic value of terahertz technology in some neuropsychiatric diseases.Although the precise underlying mechanism of the interactions between terahertz electromagnetic waves and the biosystem is not yet fully understood,the research progress in this field shows great potential for biomedical noninvasive diagnostic and therapeutic applications.However,the biosafety of terahertz radiation requires further exploration regarding its two-sided efficacy in practical applications.This review demonstrates that terahertz biotechnology has the potential to be a promising method in the field of neuropsychiatry based on its unique advantages.

Synthesized All-Pass Waveguide for Ultrafast Electronics

Engineering 2023年第11期30卷 49-54页

Ultrashort pulse transmission has been recognized as a primary problem that fundamentally hinders the development of ultrafast electronics beyond the current nanosecond timescale.This requires a transmission line or waveguide that exhibits an all-pass frequency behavior for the transmitted ultrashort pulse signals.However,this type of waveguiding structure has not yet been practically developed;groundbreaking innovations and advances in signal transmission technology are urgently required to address this scenario.Herein,we present a synthesized all-pass waveguide that demonstrates record guidedwave controlling capabilities,including eigenmode reshaping,polarization rotation,loss reduction,and dispersion improvement.We experimentally developed two waveguides for use in ultrabroad frequency ranges(direct current(DC)-to-millimeter-wave and DC-to-terahertz).Our results suggest that the waveguides can efficiently transmit picosecond electrical pulses while maintaining signal integrity.This waveguide technology is an important breakthrough in the evolution of ultrafast electronics,providing a path towards frequency-engineered ultrashort pulses for low-loss and low-dispersion transmissions.
