Hi,

I need to design a coplanar waveguide for proper microwave magnetic field urgently.

The basic configure is simple as below:

50 nm thick Gold (Au) CPW on Si substrate;
The gap and the signal line are 10 microns respectively, resulting in 1:1 ratio for 50 ohm impedance matching.
Focused on the distribution of the magnetic field parallel to the plane of the signal line.

I am still at the learning phase of HFSS. I 've drawn the structure as I described, but I failed to use the lumped port for excitation. Please help.

Many thanks!
 

you dont know how to excite the cpw using lumped port. Is that your problem?
 

Hi thanks. I have a look first.

Hi yes. I think it is the main problem.
I've just figured out the structure in HFSS, attached. Pls have a check if you don't mind.
Actually I tried to figure it out refering to the HFSS10's user guide. Even don't know if the boundary condition I chose is correct or which example in the book I could refer to.
My purpose is just to find out how large the H field is and its distribution on top of the signal line by 23dBm input.
Thanks.
