The title of thesis is “Wire Media for Enhancement of Radiative Heat Transfer and Spontaneous Emission”
Electromagnetic metamaterials are artificial media which exhibit extraordinary elec-tromagnetic features and functionalities that are not found in nature. One of the im-portant realizations of metamaterials is called wire medium which is an optically dense array of aligned wires embedded into a dielectric matrix.
This thesis concentrates on wire medium and its use for two specific and important purposes. The first purpose is associated with radiative heat transfer, and it is the improvement of thermophotovoltaic systems (generally speaking, systems for con-version of radiative heat into electricity). The second purpose is the enhancement of radiation from subwavelength emitters.
Using wire metamaterials, the thesis paves the road towards creation of more effi-cient thermophotovoltaic generators than those known now, and in addition, its re-sults can be also useful for infrared optical sensing, for radiative cooling of small ra-diation sources, and, generally, for the whole area of nanophotonics.
