Unconventional Microwave Source

An all-silicon single-photon source by unconventional photon blockade

The lack of suitable quantum emitters in silicon and silicon-based materials has prevented the realization of room temperature, compact, stable, and integrated sources of single photons in a scalable on-chip architecture, so far. Current approaches rely on exploiting the enhanced optical nonlinearity of silicon through light confinement or slow-light propagation, and are based on parametric pro...

Are Microwave Ovens a Source of Danger?

Radio source contributions to the microwave sky

Cross-correlations of theWilkinson Microwave Anisotropy Probe (WMAP) full sky K-, Ka-, Q-, V-, and W-band maps with the 1.4 GHz NVSS source count map and the HEAO I A2 2–10 keV full sky X-ray flux map are used to constrain rms fluctuations due to unresolved microwave sources in theWMAP frequency range. In the Q band (40.7 GHz), a lower limit, taking account of only those fluctuations correlated...

A Novel Approach for Direct Preparation of Hydroxyapatite Nanoparticles from natural source using Microwave

Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natu...

Efficiency Optimization for Phase Controlled Multi-source Microwave Oven

A solid-state microwave generators system is considered as an alternative to the magnetron, in order to inject electromagnetic energy into the cavity of a microwave oven for domestic use. Over current devices, the use of solid state technology allows to control the frequency and phase of the electromagnetic field generated. Considering a simplified cavity with 2 solid state sources, the influen...
