Multiple poles resonances coupling with high sensitivity sensing for multiple bulging black phosphorus-based metasurface

open access: yesNew Journal of Physics, 2023
Herein, a multiple bulging black phosphorus (BP)-based metasurface is proposed for studying its reflection responses and sensing performances through the finite-difference time-domain simulation method. It is shown that, the reflection dips are caused by

What is the signal in signal detection? [PDF]

open access: yesPerception & Psychophysics, 1974
This study concerns the nature of the stimulus represented along the decision axis in the yes/no auditory detection task. Two contrasting interpretations, absolute and difference representation of the stimulus, are tested by raising the carrier tone embedded within the background "noise" to the level of the signal, on occasional "catch" trials.
