Fingerprint matrices transform scattered light into clear images, overcoming challenges in opaque environments and paving the ...

An efficient method of moments (MoM) based on polynomial chaos expansion (PCE) is applied to quickly calculate the electromagnetic scattering problems. The triangle basic functions are used to ...

Abstract: The Wigner–Smith (WS) time delay matrix relates a system’s scattering matrix to its frequency derivative and gives rise to the so-called WS modes that experience well-defined group delays ...

In this work, we overcome these limitations. Our method requires no trial and error, thus much easier to use: provided a photonic structure and a user-specified accuracy level (i.e., a real number), ...

Particles with internal inclusions or cores are ubiquitous in the atmosphere. One example is dust particles coated with water-soluble aerosols such as sulfate or nitrate. For these particles, the dust ...

The actress synonymous with Trinity faced the weight of expectations when she reunited with Keanu Reeves and Lana Wachowski for the new sequel. Carrie-Anne Moss said she “let go of any construct in my ...

2D and 3D scalar finite-difference frequency-domain solver of the scattering matrix with the recursive Green's function method. Wave-transfer matrix and scattering matrix toolbox. Can be used for ...

Abstract: Ultrasonic array imaging is used in nondestructive testing for the detection and characterization of defects. The scattering behavior of any feature can be described by a matrix of ...

Ultrasound is a flexible and powerful medical imaging tool. However, variations in organ tissue structure cause propagating waves to undergo unexpected phase shifts, resulting in aberration (blurring) ...
