MetamaterialsMetamaterials are composite materials with exotic properties. So far two types of metamaterials are most studied:



{Electromagnetism in vacuum and curved

spacetime

Electromagnetism in flat spacetime

Medium (related to geometry)Diffeomorphism

EM metamaterials

Relativistic Celestial Mechanics



Space technologies are becoming mature enough for a new generation of tests of GR within the Solar System.




New evidence requires to refine our understanding of the relativistic corrections to Newtonian Celestial Mechanics.





We revisited the EIH equations for the reduced two (spinning) body problem using a powerful Hamiltonian method.





We revisited the EIH equations for the reduced two (spinning) body problem using a powerful Hamiltonian method.

We solve exactly for the first time the full 2PN EIH equations.



Using our method we reproduce all the known relativistic corrections...

Perspectives


PerspectivesDevelopment of design technique for acoustic metamaterials comparable with the one for EM metamaterials.



Further develop our new approach to Relativistic Celestial Mechanics to investigate more complex systems.




Further refine the RPS concept (see Pacôme presentation).





Some future projects involving:






a new approach to nuclear fusion based on some newly discovered properties of plasmas;






a new approach to nuclear fusion based on some newly discovered properties of plasmas;

novel wireless power transmission approach based on new aspects of laser physics.
