Mathematical analysis of the two dimensional active exterior cloaking in the quasistatic regime
Fernando Guevara Vasquez, Graeme W. Milton, Daniel Onofrei
We design a device that generates fields canceling out a known probing field inside a region to be cloaked while generating very small fields far away from the device. The fields w…
Resistor network approaches to electrical impedance tomography
Liliana Borcea, Vladimir Druskin, Fernando Guevara Vasquez +1
We review a resistor network approach to the numerical solution of the inverse problem of electrical impedance tomography (EIT). The networks arise in the context of finite volume…
Transformation elastodynamics and active exterior acoustic cloaking
Fernando Guevara Vasquez, Graeme W. Milton, Daniel Onofrei +1
This chapter consists of three parts. In the first part we recall the elastodynamic equations under coordinate transformations. The idea is to use coordinate transformations to man…
Study of noise effects in electrical impedance tomography with resistor networks
Liliana Borcea, Fernando Guevara Vasquez, Alexander V. Mamonov
We present a study of the numerical solution of the two dimensional electrical impedance tomography problem, with noisy measurements of the Dirichlet to Neumann map. The inversion…
