Patent

CA 2482083

There is provided a complex frequency response filter providing a frequency response having a desired shape. A first complex frequency response filter includes a first and a second reflecting surfaces (22, 24) defining a resonant cavity therebetween. Each of the reflecting surfaces respectively has a predetermined surface finish providing a given reflectivity (34, 36). In another embodiment, the complex frequency response filter includes a transmission medium and a first and a second reflecting surfaces defining a resonant cavity therebetween. A method for manufacturing such devices is also disclosed.

L'invention concerne un filtre à réponse de fréquence complexe fournissant une réponse de fréquence de forme voulue. Un premier filtre à réponse de fréquence complexe comprend des première et deuxième surfaces réfléchissantes (22, 24) définissant une cavité résonante entre elles. Chacune de ces surfaces réfléchissantes possède respectivement un fini superficiel prédéterminé permettant une réflectivité donnée (34, 36). Dans un autre mode de réalisation, le filtre à réponse de fréquence complexe comprend un support de transmission et des première et deuxième surfaces réfléchissantes définissant une cavité résonante entre elles. Un procédé de fabrication desdits dispositifs est également décrit.
