Hi
I am new kwave user. Got some questions, I appreciate your answers in advance and it means a lot.
1-I went through all examples, I saw no particle in the photoacoustic simulation let alone a Janus particle. I want to know if is there any way to simulate the Janus particle.
2-I could not find an example where it is explaine how a gaussian pulse is simulated. what I understood is that I have to define a gaussian function with my laser parameters and then multiply the gaussian function into source.p0, but I still get various error such as dimensions. Is there an example where it is explaiend? I found people shared their codes and they simulated it.
3-I also noticed that I have to define a initial pressure, I understand it is needed to solve the differential equation, since I have no clue what is the value, is there any way to simulate the phenomenon and have a good approximation of the generated wave?
P.S. what I want to do is simulate a laser (15ns) pulse which illuminates on a janus particle. even if I simulate a disk of gold it is ok. So I realized I can use the axisymmetric example, and change the density and sound speed to gold values, but I dont know how I can make it a work with pulse mode laser. thank you.
