| The effect of different f numbers on the focusing performance in the attenuative medium is further investigated. |
| This paper presents a parametric study on the efficiency of ultrasound focusing in an attenuative medium, using phased arrays. |
| For example, an optional square wave pulser can be supplied for applications involving the inspection of highly attenuative material, such as castings and forgings. |
| However, in most cases wave propagation from the crack to the sensor is attenuative and dispersive. |
| Specifically, an analytical model of ultrasound wave focusing in a homogeneous, isotropic and attenuative fluid with point sources is presented. |
| The area is underlain by competent attenuative clayey and red lateritic soils. |
