Abstract: This paper presents the compact design of a reflective-type noninvasive microwave sensor using an omega-type slot in the ground plane for accurate unknown dielectric material (UDM) ...

Add rotational sensing - without a mechanical connection - with the Adafruit AS5600 Magnetic Angle Sensor. Featuring the classic ams AS5600, this board can sense a rotating N/S magnetic field up to ...

This paper reports a biochemical sensor based on the quasi-bound states in the continuum (quasi-BIC) mode of a reflective secondary metagrating in the visible light band. Different from conventional ...

New optical sensor using differential guided-mode resonance achieves record sensitivity and portability, enabling real-time ...

A new method fuses Phase Measuring Deflectometry and Shape from Polarization, enabling precise 3D imaging of specular ...
