   Hi,

   Could you please let me know what the the simulation frequency range of the source? For example, I was wondering if the kspaceFirstOrder2D or kspaceFirstOrder3D could be used to simulate an acoustic source with frequency as low as e.g. 1 Hz to 100 Hz (i.e. it is not an ultrasound source but it is an acoustic source)?

   Many thanks and have a good day.

   Hi,I have successfully used the kspaceFirstOrder2D to simulate an acoustic source with frequency 20hz,and you should change the number of grid points and the grid point spacing.

   Hi Liwen,

   Thank you very much for the information and suggestions. BTW, I was wondering if you know how to use "time reversal" with kspaceFirstOrder2D since I didn't find an example for it?

   Many thanks and have a good day.

   Hi John,

   If you open the k-Wave help in the MATLAB help browser, you can find two examples of time reversal using kspaceFirstOrder2D (2D Time Reversal Reconstruction For A Line Sensor and 2D Time Reversal Reconstruction For A Circular Sensor).
