SiGe Microwave Phototransistors for Microwave-Photonics Applications
2020 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS), 2020This paper gives an overview on the development of microwave phototransistors within SiGe Bipolar and BiCMOS technologies. The physics and design of SiGe/Si Heterojunction Bipolar Phototransistors (HPT) are covered. A comprehensive analysis of the photodetection mechanisms and its localization into the structure is provided.

The Microwave Absorbing Phenomena Of Ferrite Microwave Absorber
[1993] Digests of International Magnetics Conference, 1993The complex permeability dispersions and the microwave absorbing phenomena are investigated in ferrite microwave absorbers. The complex permeability of hexagonal (Y- and Z-type) and spinel (NiZn ferrite and NiZnCo ferrite) ferrite microwave absorbers were measured in 200 MHz-16 GHz range.

Various uses of the microwave spectrum are discussed. The first realisation was communications across the Channel by British and French engineers in 1931. During the Second World War enormous effort was expended to harness microwaves for radar. The research work was often done with limited resources (a poem by one of the participants describes the ...

Reviews of Modern Physics, 1948
The spectroscopist in the past has been a fortunate fellow. When he could no longer find something new to measure with his old spectrometer (or if he became bored with repeated use of the same old frequencies) he could always move on to a new place in the spectrum, provided of course that he could generate and detect radiation there.

Self-folding of polymer sheets using microwaves and graphene ink
, 2015Self-folding represents an attractive way to convert two-dimensional (2D) material sheets into three-dimensional (3D) objects in a hands-free manner. This paper demonstrates a simple approach to self-fold thin pre-strained polystyrene (PS) sheets using ...

Reducing Microwave Absorption with Chaotic Microwaves
2017We study the response of a two-level quantum system to a chaotic signal using numerical methods and compare it to the response to a sinusoidal signal. We expect the largest response for sinusoidal driving functions, because the Schrodinger equation is linear. The method is based on numerical solutions of the Schrodinger solution of the two-level system,

Influence of microwaves treatment of rapeseed on phenolic compounds and canolol content.
Journal of Agricultural and Food Chemistry, 2014Rapeseeds were treated with microwaves under 800 W for 0, 1, 2, 3, 4, 5, 6, 7, and 8 min at a frequency of 2450 MHz, and oil was extracted with a press to investigate the influence on phenolic compounds, including sinapine, the main free phenolic acids ...

Hearing microwaves: the microwave auditory phenomenon
IEEE Antennas and Propagation Magazine, 2001The microwave auditory phenomenon, or the microwave hearing effect, pertains to the hearing of short pulses of modulated microwave radiation at high peak power by humans and laboratory animals. Anecdotal and journalistic reports of the hearing of microwave pulses persisted throughout the 1940s; and 1950s.
