I am using FEKO lite to simulate the characteristic modes of a dielectric resonator antenna (similar to example A-15 in the example guide). 

First question: What is the value of resonant frequencies (in GHz) that the model solver solves for?

Second question: I am getting an error: 

ERROR   37590: The characteristic modes that were calculated are all non-radiating. Increase the number of modes requested.

Even after increasing the number of modes to 100 (a physically ridiculous number), the error persists.


Thank you for the help. I need to verify if FEKO can solve for complex eigenfrequencies (frequency and damping) before purchasing it for our project.

Hi Taimur


As you are in the process of evaluating FEKO for your project I would suggest that you contact FEKO Support directly with your technical questions.
