Hi,
I hope you are well. I have a question regarding a simulation in CST. The simulation is as follows:

A cylinder with a radius of 4 cm and height of 12 cm is placed at the center of the coordinate system and in the z-axis direction i.e. one end of the cylinder is at z = -6 cm and the other end at z = 6 cm. The permittivity of the cylinder is equal to 10. Another smaller cylinder with permittivity of 50, a radius of 0.25 cm and height of 12 cm is placed like the first cylinder in the z-axis direction but its center is at x = 2 cm and y = 0. It is in the first cylinder.

I need to place a source at x = 6 cm, y = 0 and z = 0 and excite it with a fifth-derivative Gaussian pulse. This pulse will impinge on the cylinders and will be reflected.

1. How should I define such a source?
2. How can I receive the reflected pulse signal where the source is placed?

Thanks in advance.
