   Hi
   I have two problems when I using k wave to simulation.
   (1)I defined a spot that could be used as source and senor.I want this point to transmit ultrasound and pass through different medium ,then receive echo signals.The problem is that the signals I received has got a large amplitude at the t=0 time.I try to transmit a new ultrasound in single medium and use the first signal subtract the second,but the result still has got a large amplitude at the t=0 time(smaller then once),it is confusing to me.
   (2)I made a seris of spot in a line to build a Phased arry in 2D.I use source.u_mask to avoid adjacent elements receiving transmitted signals but in the received signals there still exist amplitude at the t=0 time.I wonder how can I only get the echo signals.
   Thank for your brilliant toolbox and forward to the reply.
   Best wishes
