Abstract: It is desirable to impart certain electromagnetic (light) responses to the surface of objects. The responses can be engineered in the visible, IR, THz or radio frequency range, depending on the specific applications. For example, objects with certain color appearances can be more appealing than others; windows that can control the transmission of visible light but reflecting/absorbing IR light, and building surfaces that can harvest sunlight and generate electric power are highly desirable for greater building/vehicle energy efficiency; surfaces with broadband RF absorptions can achieve stealth functionality; surface coating that can suppress the IR radiation but allow sunlight absorption are ideal for concentrated solar application, and could lead to more energy efficient incandescent light emitters. It is now possible to engineer these electromagnetic responses by designing structures using dielectric and metallic elements. This talk will present the guiding principles for achieving some of these electromagnetic responses, and also discuss fabrication methods that could be scalable to practical manufacturing.
