Abstract
Modern technology and design methodologies have unlocked new possibilities in the design and fabrication of multi-functional electromagnetic particles and surfaces. These novel technologies are capable of producing unique electromagnetic phenomena across a broad swath of the electromagnetic spectrum. In this dissertation, I will describe the design and fabrication of tunable infrared obscurants, transparent wideband electromagnetic interference shielding, and form-birefringent diffractive optical elements through the use of various advanced manufacturing methods. The maturation of the growing field of additive manufacturing has greatly increased our ability to precisely fabricate sub-wavelength features across the electromagnetic spectrum not previously possible through conventional means. By incorporating these new manufacturing capabilities into an optimized design process, it is possible to create passive electromagnetic elements that improve upon our ability to control electromagnetic wave propagation in a number of practical devices.
