The calculation principle and algorithm of boundary element method (BEM) for calculating the electromagnetic vector fields of sub-wavelength optical structures are studied. A two-dimensional computer program was developed to study the near-field and energy density distributions of the probes used in
## Abstract A nonβperturbing, fast, lowβcost probe for nearβfield measurements is presented in this paper. The new sensing technique's capabilities in antenna fault diagnosis and direct measurement of field intensity distribution at subwavelength distance from the sources are demonstrated by test m
