A new optical millimeter-wave generation scheme to double the beating frequency without suppressing the carrier by taking advantages of the out-of-phase property between sidebands of a phase-modulated ...

Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 ...

Thus, our study proposed a tangible optical air-gap attack methodology, harnessing readily available optical mediums within closed networks. Intricate measurement metrics that consider vital factors ...
