mm-Wave Ring Resonator

[@arunavenue]

any help in opti fdtd simulation for ring resonator

[@felipegerhaotaviano869]

A question, what are the steps used in create project template in CST to do the simulations?

[@EC_NURULIZZAHIZZATY]

hey, why i can't select to cut MSL?

[@oueslatiafef434]

can you do the same design on HFSS please ?

[@Fan-vk9gx]

Sorry, my HFSS license had expired. The design can be imported into HFSS. If you need it, I can email it to you.

Hey, I keep getting an error message that says 'Maximum number of pulse widths simulated, solver stopped. Please note that the steady state criterion has not been met.' I am using the student version of cst and I see a lot of ripples in my S parameters. Any help is greatly appreciated.

[@Fan-vk9gx]

There are should have enough space between the port and the 'first' discontinuity of the structure in simulation, otherwise it will give you an error in high possibility. But in practice, it is not a problem.

[@JawadAhmadKhan]

good work, but one thing i notice is that the mmWave ranges from 30-300 GHz while you are calling 15 GHz a mmWave in the title.

[@paroperha]

Simple question, how did you get the simulation animation at the start?

[@paroperha]

I found out: You set up monitors in the simulation tab (E-field, at the frequencies 3, 5, 15). But its all... pixelated, low resolution? This might be because I am using the student edition.

Thanks for your sharing. But I can't get the same result， especially S11， and the animation. Can you sent your files to me or can you help me check my design? Thanks

[@Fan-vk9gx]

Give me a downloaded link, or share your design with me.I can help you check your design.

Dear Fan, If the operating frequency is 28 GHz. Then by calculating radius according to the given equation is r= 1.150 mm. I am using Rogers RT 5880 (Lossy) substrate having epsilon 2.2 and height is 0.787 mm and t= 0.035 mm. The width calculated = 2.18 mm. Here is width of strip is greater than the radius. Please comment what should do now. Your response will be appreciated. Thank you

Highly recommend you to visit this web: web.tuke.sk/fei-ldipv/microstrip/#start This university made a really useful GUI to help us design the ring. Hope this can help you. Cheers!

what's your boundary condition of this model?

How can this resonator works for metal detection in drinking water...????

[@Fan-vk9gx]

Sorry Danish, I don't get your point. Can you describe the application scenario with more details? If you want to check whether there is some metal power in a glass of water. You can measure the permittivity or permeability of the "sample". You also need to measure the permittivity or permeability of clean water. Next, you need to compare these two measurement results. If you wan to make sure which kink of metal are in the drink water, and the percentage of each metal, this ring resonant method might not be a good choice. We can discuss this later when I have more details about your application scenario. I have threes experience on materials characterization. Maybe I can give you a hint.
