Low-frequency Dielectric Properties of Biological Tissues: a Review with Some New Insights
نویسندگان
چکیده
Low-frequency dielectric properties of biological tissues, characterized by αand β-dispersions, are reviewed with emphasis on physical mechanisms. Ion activities, tissue microstructure and composition are discussed. A new mechanism associated with membrane permeability is included. The counterion layer (electrical double layer) phenomenon is discussed. Electrode polarization, which always causes problems with low-frequency dielectric measurements, is also discussed.

Numerical Modeling of a Metamaterial Biosensor for Cancer Tissues Detection
In this paper, the numerical design and simulate a biosensor to detect tumors and cancerous tissues by using metamaterial structures in the microwave regime are presented. The presented structure consists of a microstrip transmission line and a split ring resonator (SRR) that form a bandpass filter and has a unique resonance frequency. Given that cancerous tissues have larger volumes of water t...

متن کاملDielectric properties of plasma sprayed silicates subjected to additional annealing
Several silicate materials were plasma sprayed and characterized by the authors in recent years from the point of view of their chemical and phase compositions, microstructure and mechanical as well as thermal properties. Present work is concerned with selected dielectric properties of these deposits. Synthetic mullite and steatite as well as natural olivine-forsterite were plasma sprayed using...
متن کاملMicrowave Characterization of Frequency and Temperature Dependences of Beef Bone Dielectric Properties Using Waveguide Measurement System
The article focuses on the measurement and calculation of dielectric properties of biological tissue in the frequency band 4,5 GHz – 16 GHz. Special attention is paid to the frequency and thermal dependence dielectric constant and loss factor. Observed frequency changes of biological tissue dielectric properties obey causality, i.e. Kramers-Krönig relationships which relate changes of dielectri...
