Can you help me in use of the m/w/o

I don't know how to deal with the bends of hairpin filter of microstrip ,and optimize EM structure by the software of microwave office
Thanks.

Hi,

MWO doesn't allow EM structure optimisation (yet). You could try to use X-models for your discontinuities in the linear simulation (they are based on EM simulations and are the most accurate). Than you can tune and optimize them. You have to fill the EM interpolation tables previously for your substrate material.
Or you can simulate your filter structure in Sonnet, then you can define parameters and optimise the dimentions of your structure.
