“…A favorable situation is light reflection/transmission by a layered bianisotropic medium. These conditions are often met for homogeneous bianisotropic systems such as certain crystals and also in other structurally bianisotropic systems such as helicoidal nanonostructures [44][45][46][47] or liquid crystals [48]. A suitable matrix calculus was developed by Berreman [42] and it has the advantage that it "naturally" incorporates a bianisotropic set of constitutive relations [49,50].…”

Mueller Matrix polarimetry is a powerful optical technique for the characterization of both anisotropic and bianisotropic materials. This review emphasizes methods for the interpretation of measured Mueller matrices, from the meanings of matrix symmetries, to ab initio calculations of Mueller matrices that begin with Maxwell's equations operating on materials with permittivity, permeability and magnetoelectric constitutive tensors. We present an overview of polarimetry measurements in crystals as well as metamaterials that have optically responsive features on the order of the wavelength of visible light. Examples of the full measurement of the constitutive tensors of bianisotropic media from the analysis of their Mueller matrix, collected either in transmission or reflection, are illustrated for natural c rystals, polycrystals and nanofabricated metamaterials. Experimental and theoretical research into the complex optical responses of bianisotropic materials with polarized light is best expressed in terms of the Mueller matrix, as it offers an unambiguous and mathematically robust platform for analysis of light-matter interactions.

“…(1) is a valid approximation in the range of values of CDE that we are studying. The real values of the CDE can be extracted from the differential Mueller matrix elements [31,[35][36][37]. It should be mentioned that the sources of the optical anisotropy are the preferential in plane ordering of the structures in the array configuration, as well as effects to the overlapping dimer.…”

We have studied the optical response of chiral metastructures composed of a disordered array of couples of plasmonic Au nanorods helically piled along the vertical direction. The fabrication is based on the use of multiaxial and multimaterial evaporation of the different metastructure building blocks through nanohole masks. From the analysis of the Mueller Matrix elements of the system, obtained both experimentally and from dedicated numerical simulations in forward and backward illumination conditions, we have been able to determine the linear and circular dichroic response of the system, as well as to sort out the optical anisotropy and intrinsic circular dichroism contributions to the circular differential extinction. We have also analyzed the dependence of the optical properties as a function of the angle between the rods and of the thickness of the dielectric separator. The study of quasiplanar as well as three-dimensional structures allows unraveling the role played by interactions between the constituting building blocks and, in particular, the distance between rods. We have experimentally and theoretically observed a decrease of the circular dichroic contribution and a change of the optical anisotropic contribution when the structures evolve from non-planar to planar.

“…The preliminary differential Mueller matrix plot of the nanocrystalline cellulose (NCC) obtained from the hydrolysis of cotton-derived cellulose (Figures 2P,Q) measured with the new B23 MMP tower for imaging facility (Figure 2O) confirmed that indeed all polarization contributions, LD, LB, CD, and CB were present in the 2D CDi plot illustrated in Figure 2L with the use of B23 CDi tower. The CD elements of the differential Mueller Matrix were analyzed following the method developed by Arteaga of Kahr's group (Arteaga et al, 2012) and Ossikovski group (Arwin et al, 2016). Although the two elements in the antidiagonal representing the CD maps (Figure 2R) were both homogeneous in terms of uniform red colour associated to positive CD, the intensity magnitudes were slightly different due to depolarization (Azzam, 1978).…”

CD Imaging at High Spatial Resolution at Diamond B23 Beamline: Evolution and Applications

Circular Dichroism imaging in the 190–650 nm spectral region pionered at Diamond Light Source B23 beamline, has been made possible by the highly collimated microbeam generated at the beamline and has been used to study the homogeneity of the supramolecular structures of thin films of chiral materials deposited on fused quartz substrates. This facility has been expanded with the installation of a Mueller Matrix Polarimeter, MMP, coupled to the beamlight, of which a preliminary data will be discussed. In the solid state, the measurement of CD related to the supramolecular structure is hampered by the presence of circular birefringence, linear dichroism, and linear birefringence that can only be evaluated using the MMP technique. The ability to characterize the chiroptical property of thin chiral films prepared under a variety of conditions and protocols such as drop cast, spin coating, spray at different temperatures and concentrations will enable the determination of the critical parameters for reproducible, uniform and homogeneous specimen preparation, which is the sine qua non for any commercial application. This is of particular importance for optoelectronic materials, but it can also be extended to a broad variety of materials with applications from biosensors to biological tissues.
