Simulating Kinetic Inductance in Microwave Office

Hello all,

I am working on a project which requires me to simulate superconducting nanowires, whose reactance is dominated by kinetic inductance, in AWR Microwave Office. In order to model this, I would like to create a material which has a certain excess sheet inductance, but I am struggling with how to do this. I know that this is possible because there are several papers who claim to simulate these nanowires with AWR Microwave Office (Ex.: https://arxiv.org/pdf/1602.06895.pdf). I know that you can define impedances with excess surface reactance, but this does not work for me because I need the reactance to be frequency dependent. I would greatly appreciate any guidance on how to proceed.

Thanks,

Sam

Hi spr123456,

Have you looked at the Analyst 3D editor? You can define materials and set their material properties to equations that can be frequency dependent using the _FREQ variable.

Here is a helpful page on the Analyst 3D editor: awrcorp.com/.../em_analyst.html

Thanks for your response. Is there some more detailed documentation about using impedance material definitions in Analyst 3D? I keep getting errors when I try to simulate (about boundary conditions). Thanks.
