Synthesizing quasi-bound states in the continuum in epsilon-near-zero layered materials
Giuseppe Castaldi, Massimo Moccia, Vincenzo Galdi
Bound states in the continuum (BIC) are highly confined, nonradiative modes that can exist in open structures, despite their potential compatibility and coupling with the radiation…
Exceptional Points in the Flatland: A Non-Hermitian Line-Wave Scenario
Massimo Moccia, Giuseppe Castaldi, Francesco Monticone +1
Line waves are recently discovered wave entities that are localized along two directions, and therefore can be viewed as the one-dimensional counterpart of surface waves. These wav…
Surface-Wave Propagation on Non-Hermitian Metasurfaces with Extreme Anisotropy
Marino Coppolaro, Massimo Moccia, Giuseppe Castaldi +2
Electromagnetic metasurfaces enable the advanced control of surface-wave propagation by spatially tailoring the local surface reactance. Interestingly, tailoring the surface resist…
