Near field of scattering by a hollow semi-infinite cylinder and its application to sensor booms

The Wiener-Hopf technique is employed to derive the near-field solution for scattering by a semi-infinite conducting tube due to an axially incident plane wave. Numerical results are included and emphasis is given to the interpretation of the results in terms of the error in the measurement of the magnetic field due to the presence of the sensor boom. It is found that at interior resonance frequencies the measurement error can be as large as 100 percent in the immediate neighborhood of the end of the boom. Guidelines for reducing such errors are suggested.
