Designing Band Gaps with Randomly Distributed Sub-Wavelength Helmholtz Resonators
Paulo S. Piva, Art L. Gower, I. David Abrahams
It is well-known that band gaps, in the frequency domain, can be achieved by using periodic metamaterials. However it has been challenging to design materials with broad band gaps…
Acoustic waves in a halfspace material filled with random particulate
Paulo S. Piva, Kevish K. Napal, Art L. Gower
Particulate materials include powders, emulsions, composites, and many others. This is why measuring these has become important for both industry and scientific applications. For i…
Revisiting the Sleeping Beauty problem
Paulo S. Piva, Gabriel Ruffolo
The Sleeping Beauty problem is a probability riddle with no definite solution for more than two decades and its solution is of great interest in many fields of knowledge. There are…
Effective T-matrix of a cylinder filled with a random 2 dimensional particulate
K. K. Napal, P. S. Piva, A. L. Gower
When a wave, such as sound or light, scatters within a densely packed particulate, it can be rescattered many times between the particles, which is called multiple scattering. Mult…
The average transmitted wave in random particulate materials
Aris Karnezis, Paulo S. Piva, Art L. Gower
Microwave remote sensing is significantly altered when passing through clouds or dense ice. This phenomenon isn't unique to microwaves; for instance, ultrasound is also disrupted w…
