I am trying to pass the ultrasound signal of 40Khz through a beaker (glass/plastic) using general vaseline as a couplant but signal get reflected from boundary of the beaker. Can anyone help me how to pass the signal?
1. Try to use a container made of acrylic plate which avoided an additional reflection from the boundary.
or
2. Try to use a pencil Transducer to connect it directly with the fluid without using couplant gel.
Thanks for reply.
Can you please tell me what are the material i can use through which ultrasound can pass using vaseline as couplant?
To limit reflections at the interfaces between the glass/plastic and media of propagation on both side of the beaker wall you need to use matching layers. Check the literature on acoustic matching layers.
