Quasimodes of a chaotic elastic cavity with increasing local losses
Olivier Xeridat, Charles Poli, Olivier Legrand +2
We report non-invasive measurements of the complex field of elastic quasimodes of a silicon wafer with chaotic shape. The amplitude and phase spatial distribution of the flexural m…
Statistics of eigenfunctions in open chaotic systems: a perturbative approach
Charles Poli, Dmitry Savin, Olivier Legrand +1
We investigate the statistical properties of the complexness parameter which characterizes uniquely complexness (biorthogonality) of resonance eigenstates of open chaotic systems.…
Localized Modes in a Finite-Size Open Disordered Microwave Cavity
David Laurent, Olivier Legrand, Patrick Sebbah +2
We present measurements of the spatial intensity distribution of localized modes in a two-dimensional open microwave cavity randomly filled with cylindrical dielectric scatterers.…
Diffractive orbits in the length spectrum of a 2D microwave cavity with a small scatterer
David Laurent, Olivier Legrand, Fabrice Mortessagne
In a 2D rectangular microwave cavity dressed with one point-like scatterer, a semiclassical approach is used to analyze the spectrum in terms of periodic orbits and diffractive orb…
Complete S-matrix in a microwave cavity at room temperature
Jerome Barthelemy, Olivier Legrand, Fabrice Mortessagne
We experimentally study the widths of resonances in a two-dimensional microwave cavity at room temperature. By developing a model for the coupling antennas, we are able to discrimi…
Boundary losses and spatial statistics of complex modes in a chaotic microwave cavity
Jerome Barthelemy, Olivier Legrand, Fabrice Mortessagne
We experimentally study the various manifestations of ohmic losses in a two-dimensional microwave chaotic cavity and exhibit two different contributions to the resonance widths. We…
