Magnetostatic-Magnon Sensors for Microwave Microscopy of Biological Structures

E. Hollander[1], E. O. Kamenetskii[1], R. Shavit[1]
[1]Microwave Magnetic Laboratory, Department of Electrical and Computer Engineering, Ben Gurion University of the Negev, Beer Sheva, Israel

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is ... En savoir plus

Motion of Uncharged Particles in Electroosmotic Flow through a Wavy Cylindrical Channel

N. Qudus[1], T. Mahbub[1], S. A. Ali[1], and M. Shajahan[1]
[1] Bangladesh University of Engineering and Technology, Dhaka Bangladesh

A finite element model is employed to describe the electric potential distribution and electroosmotic flow field inside a wavy cylindrical channel. The model uses coupled Laplace and Poisson-Boltzmann to evaluate the electric potential distribution inside the channel. It also contains ... En savoir plus

RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... En savoir plus
