This page allows to simulate the Focal distance, Lateral
resolution and Depth of Field of single element transducers
This model applies for circular aperture single element transducers, with
flat or spherically focused active area
See on the bottom of this page for more details on each parameter
| Input parameters |
| Frequency |
Operating center frequency of the transducer |
| Active diameter |
Active diameter of the transducer |
| Flat active area |
Check if the transducer is flat |
| Radius of curvature |
Spherical concave radius of curvature of the active surface |
| Medium velocity |
Sound velocity in the medium in contact with the transducer |
| Output parameters |
| Wavelength |
Wavelength of the emitted beam |
| Near Field |
Near field distance |
| Focal distance |
Distance of the maximum of intensity on the beam axis |
| Beam width |
Lateral size (-6dB) of the beam in transmit/receive mode (NA=Non
Applicable*) |
| Field depth |
Field depth (-6dB) of the beam in transmit receive mode |
| *For focused transducers, the model for beam width calculation
is valid if acoustic focal distance is close to geometric focal distance
(radius of curvature). NA is displayed when the result is not applicable. |
