Dielectric Properties of Heterogeneous Media with Inclusion of Fractal Media

Athalye Surabhi Sachin [1], Muhammad Zubair [1],
[1] Singapore University of Technology and Design, Singapore

The aim of this research is to study the electrostatic properties of heterogeneous media that have fractal geometries. Currently, composite dielectrics are assumed to have regular geometric structures (integer-based dimensions) and an isotopic, homogeneous dielectric permittivity; but, ... En savoir plus

Simulating 200 kHz AC Tumor-Killing Fields with COMSOL Multiphysics®

K. W. Carlson [1], N. Paudel [2], S. Dokos [3], J. A. Tuszynski [4],

[2] IEEE, Greenville, NC, USA
[3] University of New South Wales, Sydney, NSW, Australia
[4] University of Alberta, Edmonton, AB, Canada

Alternating 200 kHz electric fields ~2 V/cm (Tumor Treating Fields, ‘TTFields’) kill cancer cells by disrupting the delicate orchestration of chromosome spindle formation, but the exact mechanism of action is unknown. The likely suspects are polarized intracellular molecules such as ... En savoir plus

Finite Element Analysis of Contact Studies of Radio Frequency MEMs Switch Membranes

J. Liu [1], V. B. Chalivendra [1], C. Goldsmith [1], W. Huang [1]
[1] University of Massachusetts - Dartmouth, Dartmouth, MA, USA

Radio frequency (RF) micro-electro mechanical system (MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact. Membrane contact surfaces have complex surface roughness patterns and the mechanical contact problem ... En savoir plus
