A small ceramic component made from a dielectric material is fundamental to the operation of filters and oscillators in several microwave systems. In microwave communications, dielectric resonator filters are used to discriminate between wanted and unwanted signal frequencies in the transmitted and received signal. When the wanted frequency is extracted and d 606 $aDielectric resonators 615 0$aDielectric resonators. 676 $a621.381332 676 $a621.381332 700 $aSebastian$b M.
