Abstract
This paper revises the methodology for enabling Circular Dichroism (CD) measurements without the need for rotating transmit or receive horns in a quasi-optical (QO) measurement setup. This is achieved by using a set of wire grid polarizers, obtaining the values of Jones matrices of the sample in order to reconstruct the co-polarized and cross-polarized transmissions through the sample under test (SUT) These transmission values can then be used to create a CD signature for a SUT possessing chiral properties.
