To calculate the beam spread angle in a rectangular beam transducer probe, you can use trigonometry. The beam spread angle can be calculated using the dimensions of the probe, usually the width and height of the rectangular aperture. You can use trigonometric functions like tangent or arcsine to determine the angle of beam spread based on the dimensions of the probe.
