From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

open access: yesAdvanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

A Review of the Use of Radio-Echo Sounding in Glaciology

Progress in Physical Geography, 2001
Radio-echo sounding (RES), or radar, is an established geophysical technique that has been, and continues to be, applied to investigate a variety of ice-mass properties. This review presents the physical theory and principles of radio-glaciology, and describes the various types of radar equipment commonly used, including modern, ground-penetrating ...

Progress report on radio echo sounding

Polar Record, 1967
This report is intended to summarize activities in radio echo sounding since the introductory paper which appeared in the Polar Record four years ago (Evans, 1963 a). The field work since that time is discussed in rough chronological order, with references to the sources of more detailed information and an assessment of the principal results.
