Description

technical field [0001] The invention relates to the technical field of steel-piercing communication, in particular to a method and device for modeling a steel-piercing channel. Background technique [0002] Wired transmission cannot be used for signal transmission through the metal walls of airtight containers (such as pipelines, pressure tanks, cabins, etc.). Because wired transmission needs to drill holes in the metal wall to allow the cables to pass through, and doing so not only destroys the integrity of the metal wall, but also destroys the airtightness of the container. Traditional wireless transmission based on electromagnetic waves (such as wireless local area network, cellular communication and other radio frequency technologies) also cannot be applied to signal transmission through metals, because the Faraday electromagnetic shielding effect of metal walls has a strong inhibitory effect on the transmission of electromagnetic waves. Since ultrasonic waves have the ...
