During the two-dimensional simulation, I used the same transmitting array elements as receiving array elements in the water. I set up three layers of media: water, acrylic, and aluminum, but the received signal is very weak. Do you have any solutions? I look forward to your reply. </p> http://www.k-wave.org/forum/topic/source-sensor-interaction#post-9158 Fri, 15 Nov 2024 09:28:14 +0000 mperezdiego 9158@http://www.k-wave.org/forum/ <p>Hi, </p> <p>I am performing a 2D elastic simulation between two media where the incident medium is a solid and the imepedance mismatch is very high. I am exciting an application specific time varying pulse. The source I am using is a 1D horizontal line and I want to sense the received echo at the exact same grid points, so I defined the sensor mask equal to the source mask. What I observe after siulation is the original pulse and then the echo. The echo is equal to the excitation pulse (totally reflected back), but the sensed sent pulse, instead of being the inverted original pulse (what I observe when the sensor and the source are in different positions), I observe a more complex waveform that then offsets the received echo too. </p> <p>I would like to know how the sensor and source are coupled in this case to give that curious waveform. I am particularly interested in that waveform because I observed it in other experimental conditions but in the echoes.</p> <p>Thank you,</p> <p>M. </p>
