Exciton Binding Energy Modulation in 2D Perovskites: A Phenomenological Keldysh Framework

Advanced Functional Materials, EarlyView.
The intrinsic screening effects are successfully decoupled from structural distortion by rigorously designing a series of 2D perovskites. This enabled us to demonstrate how the dielectric environment modulates the quasiparticle bandgap and exciton binding energy.

MULTI-RESONATOR DUAL-BAND FILTERS ON DIELECTRIC RESONATORS

Information and Telecommunication Sciences, 2015
In the current article the concept of multi-resonator dual-band filter has been described. The dual-band filters based on three and four rectangular dielectric resonators have been synthesized that functionate in  ТЕ01δ  and ТЕ02δ modes. The proposed construction benefits since it doesn’t have additional coupling elements or DR shape complication.
