Metamaterial absorber for dual-rail photonic qubit filtering

, 2019
We demonstrate manipulation of a photonic qubit, encoded in a dual-rail basis, by a plasmonic metamaterial absorber. The metamaterial is designed in a way to transmit a single photon, occupying anti-symmetric superposition of two spatial modes, without ...

Electronically Switchable Broadband Metamaterial Absorber

Scientific Reports, 2017
AbstractIn this study, the novel electronically switchable broadband metamaterial absorber, using a PIN diode, is proposed. The unit cell of the absorber was designed with a Jerusalem-cross resonator and an additive ring structure, based on the FR-4 dielectric substrate. Chip resistors and PIN diodes were used to provide both a broadband characteristic

From Artificial to Embodied and Physical Intelligence in Smart Manufacturing

Advanced Science, EarlyView.
Smart manufacturing is reframed through complementary artificial, embodied, and physical intelligence, spanning computational reasoning, perception‐action coupling, and material‐level adaptation. Their integration across design, fabrication, operation, and maintenance reveals how intelligence can be co‐designed across algorithms, embodied agents, and ...
