Abstract
A multiport network analyzer using fixed electric
probes for characterizing chiral materials is proposed. The
system is based on a previous five-port junction and modified
by adding a new probe in the perpendicular plane. The new
dual 5-port allows measuring the reflection coefficient and the
two polar transmission coefficients (for polarization parallel
and perpendicular to incident wave). The theory of five-port
analyzer network is revisited and the modifications for chiral
measurement are presented. The first results of the rotation
angle produced by different structures are also presented and a
comparison with the results obtained with a conventional
system is shown.
