STRUTTURA DICROICA DISCRIMINANTE IN FREQUENZA CON BANDA PASSANTE VARIABILE, E SUE APPLICAZIONI |
摘要 |
The structure includes at least one substrate (2) of dielectric material, at least one face of which carries an orderly and geometrically periodic array of elements of electrically conductive material or, in a converse manner, bears at least one layer (3) of conductive material having an orderly and geometrically periodic array of holes (4). The structure is characterised in that control means (5, 6; 7) are associated with the substrate (2) of dielectric material for varying the dielectric or magnetic constant of the material so as correspondingly to modify its passband. |
