Hiding under the carpet cloak

WebThis unique design allows watching outside by hiding a sensor under the carpet cloaking without being detected from the outside. To verify this unique idea, we carry out full-wave simulation with commercial software (COMSOL Multiphysics 3.5 solver). Web24 de fev. de 2024 · Dynamic spreading experiment. Dynamic electrowetting experiments were carried out on the two types of liquid and on the six different surface structures (including the flat surface). For each trial, the desired substrate was placed under a thin needle (33-gauge, 90°) with an outer diameter of 0.21 mm.

Hiding Under the Carpet: a New Strategy for Cloaking

WebIn this letter, we propose a scheme for watching the outside while hiding under a carpet cloaking based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak and allow incident light get into the carpet. Hence outside information is detected inside the cloak.
