and plans for the next 6 months.


In the DALHM project we have three scientific work packages and an extra one (WP4).

WP1 deals with the modeling and characterization of LHMs

WP2 deals with design, fabrication, creation, assessment, and test of LH structures

WP3 will try to identify several applications where the LHM technology can bring revolutionary changes

WP4 dealing with the project management and the dissemination of the results
