Max Planck really got the ball rolling for quantum physics by introducing the idea of energy coming in tiny packets, or ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, ...

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

Correcting the nonlinear frequency sweep of the tunable laser source in optical frequency domain reflectometry (OFDR) is critical for accurate measurement. It is common to correct the nonlinear ...

DAB tuning information To listen to DAB radio, you need to tune to the correct frequency to receive the service you want, just as you do with AM or FM.

In remote sensing scene classification (RSSC), a common approach to reduce processing costs is to downsample images in the spatial domain to lower resolution. However, this approach can lead to the ...

In addition, the above work could not achieve a high Q -factor and the frequency selectivity was poor, which limited its application in the fields of sensing and selective thermal imaging. We design a ...
