Hello.
i need the step by step guideline for constructing the microwave isolator in HFSS software asap.
thanks

Nova Microwave staff has a thorough understanding of the working of ferrite and magnet materials and their application to develop electronic microwave circulators and isolators. The selection of basic ferrite material and magnet material has a significant effect on the overall performance and cost of circulators and isolators. The power handling, insertion loss, and labor required to manufacture these circulators and isolators is very dependent on this material selection. The ferrite material and magnet material required for circulators and isolators; is a major cost contributor to the final circulator and isolator cost. Nova designers have developed custom programs to provide the optimum performance at the lowest cost. The detailed understanding of the circulators and isolators is as follows:
This section describes the basic operating principles of strip line junction circulators and isolators. The following information has been compiled from many technical papers. It has been summarized to present a simplified non-mathematical description that is used to highlight the operating characteristics of various circulator and isolator types. Although this paper is not intended to be a design guide it is hoped that the information presented will be useful to both the buyer and system engineers. A junction circulator is a 3-port device formed by a symmetrical Y-Junction strip line coupled to a magnetically biased ferrite material. When one of the ports is terminated, with either an internal or external termination, the device then becomes an isolator which isolates the incident and reflected signals.
Consideration of the following is necessary to understand the operation of a junction circulator or isolator.

MAGNETIC CIRCUIT
IMPEDANCE TRANSFORMATION
