Abstract

We investigate the way of detecting changes in dielectric function of biological entities in liquid phase such as living cell, neurons and proteins. These studies will be used to extract some biological mechanisms information. On this purpose, we have designed a one dimensional EBG (Electromagnetic BandGap) structure with a defect at terahertz frequencies. It is now well known that such a structure presents a transmission peak in the forbidden band with a high quality factor. Here the defect is a microchannel placed below a transmission line. We will show this BioMEMS in two configurations: (a) with classical transmission lines (CPW or Microstrip) and (b) with original transmission lines. We have recently demonstrated a way to excite a propagating mode (also known as Goubau mode) on a very thin single metal wire transmission line. For this propagating mode, the electromagnetic field is very highly confined around the metallic strip. We will briefly detail the properties of such a line and its excitation. We will then show the variations of the defect mode in the forbidden gap with the variation of the dielectric permittivity of the solution. The designed BioMEMS is in a planar topology with glass and quartz substrates.
