Material and radiation losses in structures with bound states in the continuum: Ge2Sb2Te5 as an example

Daria V. Bochek, Nikolay S. Solodovchenko, Denis A. Yavsin +3

The problem of losses in resonators is a key issue in the design and use of modern plasmonic and photonic meta-devices. We propose a spectroscopic method for determining material a…
