The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

In this work, microwave frequency measurement (MFM) is reviewed since the early stages using fully analog implementations, including its evolution to analog/digital implementations with high resolutions up 1 MHz. The review includes digital and photonics techniques, a discussion on achieved devices overall field of measuring identifying unknown signals. Several planar such as interferometers, f...

Microwave ovens and 802.11 both use the unlicensed 2.4GHz ISM (Industrial Scientific Medical) band. Microwave ovens use this frequency to heat while 802.11 uses this for communication. The use of microwave ovens in the vicinity of an 802.11 node therefore naturally affects the node's ability to communicate. In this project we investigate how microwave oven noise interacts with 802.11 communicat...

Phase noise of the period-one (P1) nonlinear dynamical oscillation in an optically injected semiconductor laser is numerically investigated. The P1 dynamics causes the laser output intensity to oscillate at a widely tunable frequency for photonic microwave generation, although the intrinsic spontaneous emission in the laser inevitably degrades the microwave signal and manifests as the oscillati...

The effects of microwave interference on the operational parameters of individual MOSFET devices on CMOS wafers were studied as microwave power and frequency were varied. The study used direct injection of microwave power into the device terminals, and the output characteristics were measured with and without the microwave interference. The study showed that injected microwave power significant...
