Tailoring the spectral reflection, absorption, and transmission of the surfaces, as well as their emission, in broadband has been attracted great attention with the recent advancements in micro/nanotechnology. Such advancements provide the opportunity of realizing structures that are comparable to wavelength in terms of geometrical dimensions, which allow manipulation of incident or emitted waves from visible to infrared spectrum in small scale. Therefore, understanding the physical mechanisms that are responsible from altered spectral behaviors achieved by various type of optical filters/coatings and designing those become equally important. Aim of this thesis is to propose design methods to selected energy and thermal applications, including daytime passive radiative cooling, broadband reflectance with refractory metals, absorption mechanisms of black silicon and high temperature broadband thermal emitter, all of which require engineering of electromagnetic spectrum in broadband. Various phenomena are considered during the design stages and utilized to evaluate the resulting characteristics. Methods used in this thesis generate novel designs to be considered in various applications
