- 요약In this thesis, I describe FReSCo (Fast Reciprocal Space Correlator), the generative algorithm I developed to create correlated disordered point patterns with prescribed correlations, and show a variety of point patterns that demonstrate the wide, unexplored design space enabled by FReSCo. Using these point patterns as representations of metamaterials, I characterize their optical properties using the coupled dipoles method. In this process, I created a new class of material structures which I call gyromorphs. Gyromorphs exhibit seemingly contradictory properties - they possess both rotational order and local isotropy. I show that gyromorphs are excellent candidates as useful optical metamaterials as they exhibit large, deep, isotropic photonic bandgaps - a characteristic useful for a variety of optoelectronic applications. In chapter 1, I introduce observables that are used to characterize and classify point patterns by their correlations. In chapter 2, I introduce FReSCo and provide the mathematics behind the algorithm. In chapter 3, I show a variety of point patterns generated using FReSCo that highlight its versatility. In particular, I introduce gyromorphs and discuss their unique statistical properties. In chapter 4, I introduce the optics of collections of small scatterers in both the single- and multiple-scattering regimes and discuss bandgaps as desirable features of optical metamaterials. In chapter 5, I discuss commonalities of candidate isotropic bandgap material structures and propose gyromorphs as a new candidate. I show optical calculations comparing gyromorphs to the previous candidates proposed in literature and demonstrate that gyromorphs are superior isotropic bandgap materials. Finally, I show how FReSCo can be used to create a variety of optical metamaterials with different functions.
