A method for evaluating a uniformity of a magnetic field generated by a magnetic coil is disclosed. The method may include providing an electrical current to the magnetic coil to generate a magnetic field; scanning and obtaining a set of signals of the magnetic field by moving a measurement probe of a scanning tool point by point within a scanning region of the magnetic field and at a scanning height; performing a spectrum analysis on the set of signals by a spectrum analyzer to extract spectrum information of the magnetic field; transferring the set of signals and the extracted spectrum information to a computer system; selecting signals of the magnetic field with one or more frequencies from the set of signals based on the extracted spectrum information by the computer system; and analyzing the uniformity of the magnetic field by analyzing the selected signals by the computer system.

A coaxial cable sensor device with periodic impedance discontinuities along the length of its cable. The cable comprises an inner conductor, insulating material disposed around the length of the inner conductor, and an outer conductor disposed around the insulating material. The periodic impedance discontinuities are created by physical deformations or material alterations to at least one of the inner conductor, the outer conductor, and the insulating material. The sensor device may be used to measure temperature, pressure, strain, and acoustic waves in building structures, and is well suited for down-hole or underwater applications.
