February 2020: Our paper on "Non-Reciprocal, Robust Surface Plasmon Polaritons on Gyrotropic Interfaces" has been published in IEEE Transaction on Antenna and Propagation. [Link]

September 2019: Do truly unidirectional surface waves exist? Recently it has been shown that unidirectionality of surface waves breaks if material nonlocality is considered. But does this mean nonlocality prevents unidirectionality even for topologically protected surface waves? In our recent work we addressed and clarified this question by considering exact solution to the problem with nonlocality and loss. Please check our recent paper published in Optica. [Link]

July 2019: Giving one invited talk and one contributed talk at the 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, in Atlanta.

June 2019: Is this possible to launch unidirectional, diffractionless and robust-to-defect surface wave beam, without the need to engineer complex photonic crystals or metamaterials? We revealed this possibility by exhausting any physical mechanism that influence the unidirectionality of surface plasmon polaritons on continuum platforms e.g., biased semiconductors. [Link]

April 2019: What is the early time dynamic of optical force experienced by an atom introduced into a nonreciprocal medium? Or even earlier, what is this force at the start of the time origin, t=0? We revealed the early time dynamic of atom-nonreciprocal environment interaction in weak and strong coupling regime by removing the Markov approximation. [Link]
