      Compact, linear, lead/lag phase shifters using negative refractive index metamaterials 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2003)
      A new type of phase shifter using cascaded sections of NRI metamaterials and PRI transmission lines is proposed, which offers some significant advantages over conventional delay lines. The phase shifter is compact in size, ...

      Model reduction of modal representations 

      Louca, Loucas S.; Xydas, E. (American Society of Mechanical Engineers (ASME), 2006)
      Dynamic analysis is extensively used to study the behavior of continuous and lumped parameter linear systems. In addition to the physical space, analyses can also be performed in the modal space where useful frequency ...
