However, processing of gyroid thin films introduces distortions experimentally, creating a mismatch between the structures created practically and those explored computationally. This work explores the impact of compression normal to the substrate (z-compression) with conserved volume in (110)-oriented plasmonic silver double gyroid thin films on CD using finite-difference time-domain (FDTD) simulations. As compression reaches fifteen percent and above, new features emerge including termination-dependent opposite-handed CD responses and, at larger compressions, shorter wavelength responses that span many surface terminations. The longest wavelength responses of the system red-shift with increasing compression. The top surface structure contributes strongly to the emerging opposite-handed features and red-shifting of wavelengths. However, the less surface termination dependent features arise from a mixture of contributions from the top surface and interior of the films. Interplay of these leads to CD-switching phenomena as a function of compression for certain terminations and wavelengths. When alternative methods are utilized to compress the system, such as compression with a Poisson’s ratio of 0.33 (comparable to polystyrene) or the generation of compressed equilibrium structures with non-affine strut changes via self-consistent field theory, similar optical responses persist. Overall, this study highlights the significant impact experimentally relevant distortions (especially compression and some non-affine structural shifts) can have on the CD response of block copolymer templated plasmonic double gyroid thin films, and provides mechanistic insight into the film interior versus surface contributions to the CD response during compression.CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/optical metamaterialscircular dichroismgyroidcompressionthin filmsDatasethttps://doi.org/10.13020/rka8-vd05
