The Borders Of Embodiment: Transgression, Transformation, And Corporeality In Chicanx Speculative Fiction, Chrysta Carson Wilson

English Language and Literature ETDs

This dissertation develops a clearer vision of Chicanx Speculative Fiction (SF) as its own genre anchored to the experiences and histories of the Chicanx community, with a particular interest in the avenues through which race and gender shape the experience of embodiment. SF resists hegemonic narratives that justify racial hierarchies and reveals both the cultural and concrete pressures exerted on Chicanx bodies in the United States as a minoritized and often exploited community. Furthermore, my analysis illustrates that Chicanx writers utilize elements of SF to defamiliarize traditional notions of race, class, and nationality. Through the use of defamiliarization, Chicanx SF …

Optical Responses Of Hybrid Electromagnetic Nanostructures, Dominic Bosomtwi

Optical Science and Engineering ETDs

Fano resonances result from the interference between a broad background and a narrow state, producing asymmetric scattering profiles. Under specific conditions, destructive interference collapses the Fano resonance width, leading to bound states in the continuum (BICs) that localize light within a nanostructure while maintaining an infinitely high-quality factor (Q-factor).

This dissertation explores the design of nanostructures with multilayer hybrid plasmonic-dielectric metasurfaces using full-wave numerical simulations, facilitating multiple Fano resonances and BICs. By adjusting nanoantenna dimensions, multiple modes are excited at plasmonic-dielectric interfaces, leading to strong interactions and hybridization of energy levels, manifested as Rabi splitting.
