Help me fix a MWO project with Split Ring Resonators

Hi everyone,

Can someone tell me why i cant simulate my EMｓｔｒｕｃｔｕｒｅ．．Ｉｔ　ａｌｗａｙｓ　ｓｉｍｕｌａｔｅ　ｉｎ　ｐｒｏｃｅｓｓ　ａｎｄ　ｔｈｅ ｎ　ｈａｎｇ．．．Ａｓｋｉｎｇ　ｍｅ　ｔｏ　ｓａｖｅ　ｉｔ　ｉｎ　ａ　ｎｅｗ　ｎａｍｅ　ｔｈｅｎ　ｇ ｅｔ　ｄｕｍｐｅｄ　ｓｔｒｉｇｈｔ　ａｗａｙ．

Hello chailingleow,

upload your MWO project file (*.emp)...So that it will be easy to help you...

So happy that there is someone to help me..thanx

This project required Split Ring Resonator act as multiple stop band filters. Project include design and analysis of 2 types of Split Ring Resonator with different shapes, tunable circular and rectangular to compare its simulation results. Tunable circular and square split ring resonators (SRR) must develop a stop band that is enough to cover the bandwidth of either one of the ISM band (2.4 ISM, 5.2 GHz ISM or 5.8 GHz ISM).

The emp that have problem here is the initial draft of circular..I am just drawing refer to "Effective negative ε stopband microstrip lines based on complementary split ring resonators".

If u have any idea how should the design be done, ps advise.

PS:
As below

Hello chailingleow,

I found couple of issues with the MWO project file...
1. the dielectic constant Er was wrongly set 102 instead of Er=10.2
2. The Top Enclosure boundry setting was set to Open, it needs to be PEC to account for box resonances or to replacate circuit analysis
Approximately Open option you need to set for Antenna structures...
3. the Grid size was too fine & was set to 0.05 hence it takes lot of memory & time for the simulation....I think for your case you can set the X=Y=0.1
and use the advance mesh & EMSight options to simulate quickly & reasonable accurate....
4. I have attached the modified MWO project file & corresponding results for your refernce...
5. Also if you have the access of Sonnet em simulator then you can simulate at Grid Size/Cell Size=0.05 & you can use the advanced Conformal Meshing option to quickly & accurately analyse...
6. I even attached the Sonnet results...

Hi Manjunatha_hv,

Thank you a help for your help! But i cannot open the em structure because i just have mwo 2006 only.Between, I am doing the design for filter, is the setting still the same?

Hello chailingleow,

Yes, for Filter design using AWR MWO you should follow the similar settings...
I have attached the MWO project file which works fine in V6.5x...

Hi Manju,
Feel so grateful here

:D

I am now simulating it..hopefully there will be result coming out..

I am new to the electromagnetic as well as simulating tools.

May i ask your opinion whether i should use MWO　７．０　ｏｒ　ｉ　ｓｕｄ　ｄｏｗｎｌｏａｄ　ａｎｄ　ｕｓｅ　ｓｏｎｎｅｔ　ｌｉｔｅ？Ｉ　ｓｅ ｅ　ｉｔｓ　ｈｏｔ　ｈｅｒｅ．
