Differentiating through binarized topology changes: Second-order subpixel-smoothed projection
Giuseppe Romano, Rodrigo Arrieta, Steven G. Johnson
A key challenge in topology optimization (TopOpt) is that manufacturable structures, being inherently binary, are non-differentiable, creating a fundamental tension with gradient-b…
When can phonon modes be trapped by arbitrarily weak local defects? Rigorous sufficient conditions in a monatomic lattice
Jaden Thomas-Markarian, Jaden Thomas, Rodrigo Arrieta +3
Although many studies have shown that localized defects in vibrational lattices can trap localized phonon modes for particular geometries, there has been no general proof of locali…
Windowed Green Function MoM for Second-Kind Surface Integral Equation Formulations of Layered Media Electromagnetic Scattering Problems
Rodrigo Arrieta, Carlos Pérez-Arancibia
This paper presents a second-kind surface integral equation method for the numerical solution of frequency-domain electromagnetic scattering problems by locally perturbed layered m…
