Detecting a hidden obstacle via the time domain enclosure method. A scalar wave case
Masaru Ikehata
The characterization problem of the existence of an unknown obstacle behind a known obstacle is considered by using a singe observed wave at a place where the wave is generated. Th…
On finding a buried obstacle in a layered medium via the time domain enclosure method
Masaru Ikehata, Mishio Kawashita
An inverse obstacle problem for the wave equation in a two layered medium is considered. It is assumed that the unknown obstacle is penetrable and embedded in the lower half-space.…
On finding the surface admittance of an obstacle via the time domain enclosure method
Masaru Ikehata
An inverse obstacle scattering problem for the electromagnetic wave governed by the Maxwell system over a finite time interval is considered. It is assumed that the wave satisfies…
On finding a cavity in a thermoelastic body using a single displacement measurement over a finite time interval on the surface of the body
Masaru Ikehata
A mathematical formulation of an estimation problem of a cavity inside a three-dimensional thermoelastic body using time domain data is considered. The governing equation of the pr…
Reconstruction of a source domain from the Cauchy data
Masaru Ikehata
We consider an inverse source problem for the Helmholtz equation in a bounded domain. The problem is to reconstruct the shape of the support of a source term from the Cauchy data o…
