Analytical Theory of Photon Tunneling and Near-Field Heat Transfer Between Dissimilar Materials
Kartika N. Nimje, Mariano Pascale, Georgia T. Papadakis
Near-field radiative heat transfer can exceed the blackbody limit through evanescent-mode coupling across nanoscale gaps. This enhancement underpins applications including thermoph…
Far-field heat transfer and monochromatic thermal currents in a cylindrical nonreciprocal cavity
Guillem Masdemont, Julien Legendre, Georgia T. Papadakis
Breaking Kirchhoff's law of thermal radiation yields new opportunities in one-way radiative thermal transport and circuitry. We investigate its consequences in the far-field regime…
The critical role of substrates in mitigating the power-efficiency trade-off in near-field thermophotovoltaics
Kartika N. Nimje, Julien Legendre, Michela F. Picardi +2
Near-field thermophotovoltaic systems can achieve ultra-high power densities, however, this often comes at the cost of reduced efficiency. We show that this power-efficiency trade-…
Nonreciprocity in transmission mode with planar structures for arbitrarily polarized light
Michela F. Picardi, Vera I. Moerbeek, Mariano Pascale +1
Approaching thermodynamic limits in light harvesting requires enabling nonreciprocal thermal emission. The majority of previously reported nonreciprocal thermal emitters operate in…
