(Received 20 November 2012; revised manuscript received 17 April 2013; published 10 May 2013)We discuss the possibility of realizing utlrabroadband omnidirectional absorbers and angularly selectivecoherent thermal emitters based on properly patterned plasmonic metastructures. Instead of relying on resonantconcentrationeffectsthatinherentlylimitthebandwidth,webaseourdesignonthecombinationoftwoinherentlynonresonant effects: plasmonic Brewster funneling and adiabatic plasmonic focusing. Using this approach, wepropose compact, broadband absorption and emission spanning terahertz, infrared, and optical frequencies, idealfor various energy and defense applications.DOI: 10.1103/PhysRevB.87.205112 PACS number(s): 78
