Abstract :
In addition to the classical time-domain distortion characteristic known as fidelity, one can evaluate sensor distortion characteristic using the transformation matrix concept in linear algebra. In this paper, electromagnetic field sensor transformation matrix is calculated based on a set of Hermite- Gauss orthonormal functions. The transformation matrices are calculated for a 5-cm Asymptotic Conical Dipole (ACD), wire monopoles of lengths 5 and 8.5 cm, and L-antennas with the same heights using the simulated voltages. The simulation is performed by solving an Electric Field Integral Equation (EFIE) on wire structures using the Method of Moments (MoM). Transformation matrices are calculated for the sensors with the same level of sensitivity as a measure of distortion. Transformation matrices are compared to each other using a numerical measure.
