Calculation of iterative band-stop filters with allowance for the near fields of the ferrites
Abstract
The local-field approximation is used to study iterative band-stop ferrite filters with an arbitrary arrangement of n ferrite resonators, coupled according to both the fundamental mode and the higher modes. Calculations and experimental results are compared for devices operating at millimeter wavelengths. Good agreement is obtained, indicating the suitability of the local-field approximation.
