介质振荡器的基本结构如下图所示： 介质谐振器（Dielectric Resonator, 简称DR）放置在金属空腔中，与微带线进行耦合产生振荡的能量，谐振器的Q值已经接近金属空腔谐振器，因此介质振荡器的相位噪声较低。 介质谐振器做为DRO最 ...

In a new study in the journal Nature, Harris, Read, and their co-authors describe a previously unknown characteristic of resonators. A resonator is any object that vibrates only at a specific set of ...

Chinese researchers overcome decades-long challenge to build a laser that operates across 100-degree Celsius temperature swings.

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...
