Helium Atom Scattering from Chiral Structures
… but has been seldom applied to the study of chiral surfaces. The current thesis focuses on advancing the available theoretical and experimental tools to motivate the study of chiral surfaces using atomic beam techniques. The importance of chirality is discussed in chapter 1, along with the …

Design and fabrication of novel and functional 3D structures via proximity field nano-patterning
… to fabricate multi-dimensionally periodic micro-structures. Though a potent technique for 3D microfabrication that offers dual and superior advantage of scalable resolution and throughput, this technique has not seen broader adoption due to the lack of concerted design and fabrication strategies …

Design and measurements of novel electromagnetic properties in spiral transmission fibers
… the fiber on its optical properties. The fiber's chiral symmetry combined with its infinite translational symmetry creates a truly planar chiral structure, similar to many artificial chiral structures recently studied. The low-symmetry geometry of the fiber, which lacks any rotational and mirror …

Emission properties of radiative chiral nematic liquid crystals
… states (DOS) of the normal modes in dye-doped chiral nematic liquid crystal (LC) cells in the presence of various loss mechanisms. Losses and gain are incorporated into the transmission characteristics through the introduction of a small imaginary part in the dielectric constant perpendicular …

Free self-assembly of spontaneously chiral, supramolecular structures
… the free selfassembly of supramolecular, chiral structures. The main coarse-grained model used for this is the disc-shaped variant of the Gay-Berne potential. This is parameterised to favour face-face configurations, consistent with chromonic molecules which tend to stack due to their π − …

Understanding emergence of supramolecular chirality in lyotropic conjugated polymers
Hierarchical chiral assembly into sophisticated structures is vital for the structural complexity and functional versatility of biological systems. Inspired by the enigma of natural homochirality, the design and construction of artificial chiral hierarchical structures have garnered significant …
