Hi,
Could someone explain the elementray concept and calculations behind a fringing field sensor. As shown:
http://www.ee.washington.edu/research/seal/projects/moisture sensing/project overview.htm#how"
Taking the elementray equation behind the parallel plate arrangement to be,
C = (Eo.Er.A)/d, how does this adapt for the fringing field arrangement shown?
What is the underlying concept behind these i.e. what cause such large fringing?
Regards
Tom
