CST - Seeking Suggestions on Spherical Bending in CST & Generating Near Field Distribution Plots in different thickness

Dear Altruist,

I hope my message will find you well. 

Could you please guide me how can I do the spherical bending of different layers ( such as 2/3 tissue layers) in CST. I can do it in cylindrical fashion. I would like to know how to do it spherically in CST Studio Suite  .                         

Additionally, could you please guide how can I generate near field magnitude distribution shown below ( the attached images were generated in HFSS in one of the publications available online) in different thickness ( such as 5 mm/10mm) from the antenna–tissue interface, which includes the legend as well. It would be better if you attach any short video or step by step procedure for that. 

Please help.
