I want to extract the LCRG parameters of a structure based on a method established by S.Otto & Al. in this article "An Energy-based Circuit Parameter Extraction Method for CRLH Leaky Wave Antennas".
In simulation, i've used PMC wall (Perfect H), periodic boundaries (Master & Slave) and PML box. My first objective is to get the shunt and the series resonances frequencies (23.88 GHz, 25.30 GHz) from which i can get all the LCRG parameters.
Unfortunately this was not the case, i've got these resonance frequencies
17.38 GHz
21.89 GHz
I don't know the cause of these discrepancy with the authors results, can anyone help please, i've spent a lot of time simulating without serious success.
I've chosen these settings for my simulation:
Solution type is eigenmode.
Minimum frequency is 15 GHz.
Maximum delta frequency par pass is 0.5%
Initial Mesh Options is 0.2
This is the project done by HFSS v 14.0
