Detection of Hazardous Liquids Using Microwaves

We investigate the feasibility of using dielectric spectra to classify hazardous and nonhazardous liquids. The dielectric spectra of several liquids was obtained with a shielded-open coaxial fixture, and we present a new full-wave model for calculating the complex permittivity of liquids using this fixture. Using the measured complex permittivity for each liquid, we examine several classificati...

A Visualization Method for Breast Cancer Detection Using Microwaves

This paper proposes a qualitative approach to the inverse scattering problem of microwave tomography for breast cancer detection. In a 2D framework, the tumor inside the breast is regarded as an unknown scatterer placed inside an inhomogeneous and lossy background, formed by skin and fat. We firstly present in detail the mathematical formulation of the method, which is based on the reciprocity ...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Novel Processing of Nanostructured Ceramics Using Microwaves

Effects of Exposure to Microwaves: Problems and Perspectives*

During the last 25 years, there has been a remarkable development and increase in the number of processes and devices that utilize or emit microwaves. Such devices are used in all sectors of our society for military, industrial, telecommunications, and consumer applications. Although there is information on biologic effects and potential hazard to man from exposure to microwaves, considerable c...
