Optical Dyakonov surface waves at magnetic interfaces

“…3 In contrast to plasmons, such surface waves exist in transparent media; thus they are lossless. The special conditions at which Dyakonov resonances are found to exist in all the geometries addressed to date [3][4][5][6][7][8] are not easy to meet in practice. Therefore elucidation of strategies to enhance the existence domains is of capital importance for exploiting the properties of surface waves.…”

“…The results reveal that the existence domains are enhanced compared with those encountered in nonmagnetic materials in both interface 3,4,8 and nanolayer structures. [5][6][7] A motivation for this study is the recent development of transparent materials, such as aerogels 10 and molecularbased magnets, 11 which under proper conditions can exhibit moderately large permeability values (i.e., r Ϸ 2). In addition, the use of the metamaterials' magnetic properties 12 can also open important prospects and potential applications for Dyakonov surface waves.…”
