Hi, Dr. Mazin Mustafa,
I appreciate your kind response. Your note greatly helps me to understand my questions!

To Karthik Thothathri,
Sure, I will modify the general code and make it available in the MATLAB file exchange since the current code is only readable for me, and it might be hard for others to understand it.

To 昂 川村,
Yes, I did substrate the unbounded region solution and then manually added the terms in GEJ0. I didn't discuss this in my dissertation, but I found it useful in accelerating the numerical computations. Please take a look at my personal note (page 13 and pages 17-21): https://drive.google.com/file/d/119WYX1Y1loffDDkUtncHvfFD82p0JNpe/view

Hello Dr. Mazin Mustafa,

I'm studying your codes to modify and apply to the problem I'm investigating. I understood almost all codes but couldn't do for two points below.
- First is related to "GEJ0.m". Why should it be added to the solution by TLGFs?
- Second is integration range in the "HankelTransform.m". I saw your dissartation and understood regarding the part of "0 ~ a". Then where can I see the integration of "a ~ +infinity"?
I guess these points are related. Could you introduce some papers explaining these points?

Thanks a lot for your reply Dr. Mazin. I am quite interested in the generalised implementation. Is it possible for you to send me.

Thanks and best regards,
Karthik

To Karthik Thothathri,

The spectral domain Green functions are implemented in GEJ1-GEJ5, however, they depend on the transmission line model.
Regarding adding more layers, you are right, you can easily add more layers. If you are interested, I have a general code that can handle any number of layers and point at any location.

Hello Dr. Mazin,

I would like to clarify a doubt that I have with regards to the implementation. I understand that the spatial domain green functions are obtained by performing the double integral( through Hankel transform and single integral) of the spectral domain green functions. In the code, where is the spectral domain green's function. It would be great if you could provide your help with regards to this.

Thanks and best regards,
Karthik

I added one more layer in the configs file and it seems to be working.. Thanks again
