Alternatively, you could also create the source and sensor masks manually (i.e., set <code>source.p_mask</code> and <code>sensor.mask</code> rather than using the <code>kWaveTransducer</code> class), and define a single source time series to drive all of the elements.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/planewave-simulation#post-5472 Mon, 18 Apr 2016 04:32:17 +0000 rajeshlvvl 5472@http://www.k-wave.org/forum/ <p>Hi Brad,</p> <p>We aretrying to simulate planewave propagation in a medium using 3D model. The way we are trying to generate a planewave is by giving very high values for azimuthal focus and elevation focus as below. Is the approach right? Or is there any other way to generate them?</p> <p>Thanks<br /> -Rajesh </p> <p>transducer.focus_distance = 3000000e-3; % focus distance [m]<br /> transducer.elevation_focus_distance = 3000000e-3;% focus distance in the elevation plane [m]<br /> transducer.steering_angle = 0; % steering angle [degrees]<br /> transducer.steering_angle_max = 0; % maximum steering angle [degrees]</p> <p>% apodization<br /> transducer.transmit_apodization = 'Rectangular';<br /> transducer.receive_apodization = 'Rectangular';<br /> transducer.active_elements = ones(transducer.number_elements, 1);<br /> transducer.input_signal = input_signal; </p>
