These curves are\, in general\, continuo us mappings from a normalized one-dimensional interval [0\,1] to a normali zed two-dimensional region\, [0\,1] × [0\,1]. In each case the curve pass es through every point in the 2-D region in the limit of infinite iteratio n order. The most widely known of these curves are the ones proposed by G. Peano and David Hilbert in 1890 and 1891\, respectively. From an electrom agnetics\, scattering\, and antenna perspective\, space-filling curves are particularly attractive as they offer resonant structures with very small footprints when the step-order of iterative filling increases. However\, these curves are a subset of a broader class of curves in graph theory kno wn as Grid-Graph Hamiltonian Paths (GG-HP) and Grid-Graph Hamiltonian Cycl es (GG-HC).\n\nIn this lecture\, we will explore the fundamental electrody namics of space-filling curves and Grid-Graph Hamiltonian Paths\, focusing on their scattering properties\, polarizability\, and multiband functiona lity\, and their roles in the development of electrically small and reconf igurable antennas\, metamaterials\, and metasurfaces. Specifically\, we wi ll examine the use of space-filling curve and Hamiltonian Path fractal ele ments in designing wideband yet miniaturized top-loaded monopoles\, ultra- passive RFID tags\, polarization-insensitive high-impedance surfaces\, ele ctrically-thin microwave absorbers\, single-negative (SNG) and double-nega tive (DNG) metamaterials\, and metasurfaces with non-uniformly spaced incl usions for printed antenna beam shaping.
