METHOD FOR TUNING THE OPERATING FREQUENCY OF MICROWAVE DEVICES BASED ON CRLH () CELLS IN A CONTROLLED MANNER BY MAGNETIC POLARIZATION

The invention relates to a method for tuning the operation frequency of microwave devices based on CRLH (Composite Right/lLeft Handed) cells. According to the invention, the method consists in applying a uniform magnetic polarization field normal to the surface of a ferrite substrate used for manufacturing said device, which permits the control of an operation frequency of the device between certain limits, imposed by the electrical parameters of the substrate and the intensity of the applied magnetic field. Invenţia se referă la o metodă de acord controlat al frecvenţei de lucru a dispozitivelor de microunde cu celule CRLH (Composite Right/Left Handed). Metoda conform invenţiei constă din aplicarea unui câmp magnetic de polarizare uniform, normal, la suprafaţa unui substrat feritic, folosit pentru realizarea dispozitivului, ceea ce permite controlarea frecvenţei de lucru a dispozitivului între anumite limite, impuse de parametrii electrici ai substratului şi de intensitatea câmpului magnetic aplicat.
