Achieving Extraordinary Acoustic Transmission in a Single Slit by Boundary Impedance Engineering
J. Sumaya-Martinez, J. Mulia-Rodriguez
Extraordinary acoustic transmission is commonly associated with periodic or multi-aperture structures. In this work, we show that a single subwavelength slit can support strongly e…
Energetic vs Inference-Based Invisibility: Fisher-Information Analysis of Two-Layer Acoustic Near-Cloaks
J. Sumaya-Martinez, J. Mulia-Rodriguez
Near-cloaks based on passive coatings can strongly suppress scattered-field energy in a narrow frequency band, yet an observer's ability to infer object parameters from noisy measu…
Fisher Information as an Operational Metric for Structured Optical Beams
J. Sumaya-Martinez, J. Mulia-Rodriguez
Structured optical beams possess rich spatial features that are commonly characterized using entropic measures of field complexity. However, such measures do not directly quantify…
Topological reorganization of near-field energy flow governing scattering transitions in subwavelength rectangular grooves
J. Sumaya-Martinez, J. Mulia-Rodriguez
The scattering of electromagnetic waves by subwavelength rectangular grooves has been extensively studied, yet its physical interpretation has largely relied on field-intensity dis…
