Dielectric Properties of Materials at Microwave Frequencies

KŘIVÁNEK, I.: Dielectric properties of materials at microwave frequencies. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 5, pp. 125–132 The paper introduces the review of the present state of art in the measurement of the interaction of electromagnetic waves with diff erent kinds of materials. It is analysis of the possibilities of the measurement of the interaction of high frequen...

Dielectric properties of certain biological materials at microwave frequencies.

In the medical field, microwaves play a larger role for treatment than diagnosis. For the detection of diseases by microwave methods, it is essential to know the dielectric properties of biological materials. For the present study, a cavity perturbation technique was employed to determine the dielectric properties of these materials. Rectangular cavity resonators were used to measure the comple...

Tailoring Artificial Dielectric Materials at Terahertz Frequencies

The Submillimeter Technology Laboratory(STL) at the University of Massachusetts Lowell has developed a methodology of tailoring the complex refractive index for artificial dielectrics at terahertz frequencies. A wide range of precisely controlled optical properties have been achieved for materials such as vinyl acetate, silicone, polyethylene and epoxy resin when combined with powdered loading ...

Emulsion Inks for 3D Printing of High Porosity Materials.

Photocurable emulsion inks for use with solid freeform fabrication (SFF) to generate constructs with hierarchical porosity are presented. A high internal phase emulsion (HIPE) templating technique was utilized to prepare water-in-oil emulsions from a hydrophobic photopolymer, surfactant, and water. These HIPEs displayed strong shear thinning behavior that permitted layer-by-layer deposition int...
