@@tardisblu3.1415 thank you☺️
Actually I have to extract the values of R, L, C with Co
For that first you have to have the electromechanical coupling coefficient(kt2) and Quality factor(Q) and then using that calculate Rm, Lm and Cm. Co is the capacitance between your electrodes which is EpsilonA/d. This you can do only if you have your device or some simulation from which you can get kt2 and Q. The other way is to do it theoretically which will be more difficult, that is to find, meff, damping and keff and then with the piezoelectric transduction coefficent find it. That is anyway mentioned in the video. You can also look the book piezoelecric mems resonators by piazza, where all of this is there in detail.
Thank you so much sir@@Jyothish_Raj
Firstly I want to thank you for your reply@@Jyothish_Raj I have calculated Lm, Cm, Co. But i am finding difficulties in the calculation for Rm, Ro, Rs. Plz suggest any relevant research article or conference paper.
Sir I need to know, how to calculate the parameters of this BVD model circuit diagram...

Bhaiya IiSc ka rank itna down kyun hua 😞😞😞 IiSc Mera dream hai
Ya, got to know that the rank went down from 155 to 225. But that doesn't matter much I guess, still it has the best research facilities in the country. Due to some reasons it might be down now, but it will come up strongly. New departments are being build and growth seems to be happening. The news says that the reason for low ranking is faculty to student ratio, that is something IISC can fix quickly I guess.
@@Jyothish_Raj ohhh... Thik hai bhaiya.. thanks for your reply... Next year mai bhi Jaana chahta huu... BS mai 🙂
@@RUPAM_3_6_9 So you started +2 right now right. All the best to you😊

sir, i have a doubt regarding rayleigh velocity in ZnO, from the online data available, velocity is 3820m/s
There might be slight difference in velocities based on the slight differences in material. I mean some materials can be more crystalline than the other. I took the velocity given in the paper. It differs because of the different methods available to grow ZnO. I think that you can tell only a range, perfect number is difficult to tell unless you measure it for your sample by some experiment. Also simulations are only to give you a rough idea before the actual experiment. So you can take educated approximations.
Also note that ZnO in comsol will have a particular velocity which they might have given by looking different sources.
Thank you sir for uploading this
Hi Jyothish, Can you make a video on temperature effects on effective index of waveguide? Like adding heater element on waveguide, changing the heater bias to monitor temperature and its effects on effective index.
I haven't done this till now, will try to see if I can do it. Will make a video if I am able to do it. Thank you😊
❤ presentation and explanation commendable..🎉
hello Jyothish, I need some help in COMSOL. How should I be able to contact you?
my email id is jyothishrajendranpillai@gmail.com. You can mail me, I will try to help you if I know. I am also learning comsol, not a professional of the tool😅
This is the paper mentioned: iopscience.iop.org/article/10.1088/1742-6596/76/1/012035
