For multilayer medium with frequency-dependent dielectric properties, how to modify the time delay and image domain?

[luckyQCL]

Recently I've been doing work on brain imaging, the imaging area is circular and from the outside to the inside are 6 layers of materials with different dielectric constants and conductivities, I've modified the model of MERIT but it has been running incorrectly so I'd like to ask for some advice on making changes to the code.

I think the codes are not fit for your complex problem. And, I suggest you to find an open source for CSI. Good luck!

In fact, I saw some related papers that also used DAS or DMAS algorithms, with imaging regions that also contain multiple layers of different media. So a modification to the code of MERIT should be able to realize the imaging in multi-layer media.Besides, the conference paper "Open-source Software for Microwave Radar-based Image Reconstruction" also show that MERIT provides a number of means of synthetic focusing including assuming a finite number of media in the imaging domain each with different dielectric properties; or frequency-dependent dielectric properties
