You will be better off using a parabolic focusing system. Ultrasonics are only HF audio (around 40khz usually) & do not display the properties of microwaves which are what waveguides are intended for.

I suggest you read this document of definitions. Get familiar with beam cone and how ultrasonic sensors actually work. It covers things not covered in your other thread. Thinking about beam cone what would happen if the transmitted waves bounced off the sides of an added waveguide? You select a sensor and transmitter based on the application taking things like the environment and distance into consideration. Distance is a function of power combined with the cone. You do not use a sensor designed to measure .1 to 1 meter to measure accurately a distance of 10 meters. Read the links I provided in your other thread on this topic, they should help.
