On the Detection of Internal Defects in Structured Media
Bryl Nico M. Ong, Aarush Borker, Neil Jerome A. Egarguin +1
A critical issue that affects engineers trying to assess the structural integrity of various infrastructures, such as metal rods or acoustic ducts, is the challenge of detecting in…
Personal Sound Zones and Shielded Localized Communication through Active Acoustic Control
Neil Jerome A. Egarguin, Daniel Onofrei
In this paper, we present a time domain extension of our strategy on manipulating radiated scalar Helmholtz fields and discuss two important applied scenarios, namely (1) creating…
Feasibility Analysis for the Problem of Active Near Field/Far Field Acoustic Pattern Synthesis in Free Space and Shallow Water Environments
Chaoxian Qi, Neil Jerome A. Egarguin, Daniel Onofrei +1
In this paper, a detailed sensitivity analysis of the active manipulation scheme for scalar Helmholtz fields proposed in our previous works, in both free space and constant-depth h…
Active manipulation of Helmholtz scalar fields: Near field synthesis with directional far field control
Neil Jerome A. Egarguin, Daniel Onofrei, Chaoxian Qi +1
In this article, we propose a strategy for the active manipulation of scalar Helmholtz fields in bounded near field regions of an active source while maintaining desired radiation…
Sensitivity analysis for the active manipulation of Helmholtz fields in 3D
Neil Jerome A. Egarguin, Daniel Onofrei, Eric Platt
In this paper we continue to study the feasibility of active manipulation of Helmholtz fields and by using an improved and more robust numerical strategy we present a detailed sens…
Exact relations for Green's functions in linear PDE and boundary field equalities: a generalization of conservation laws
Graeme W. Milton, Daniel Onofrei
Many physics problems have , source , fields , satisfying differential constraints, symbolized by , where ,…
