Abstract
A method and apparatus for providing communication and/or power through a medium including a transmitter comprising a surface configured to send a signal at a controlled angle a receiver comprising a surface configured to receive the signal from the transmitter a medium between the transmitter and receiver, wherein the medium comprises a pipe, and wherein the controlled angle can be less than or greater than 90 degrees. In some embodiments, the controlled angle is tailored to allow only the first direct arrival to reach the receiver and to prevent multiple reflections from reaching the receiver. In some embodiments, the transmitter surface steers a beam to deliver the controlled angle. In some embodiments the medium is exposed to a temperature of up to 200°C and/or a pressure of up to 30,000 psi. In some embodiments the receiver surface receives a signal that comprises a frequency of 1-20 MHz or a frequency of about 5 to about 15 MHz.
