It is shown that numerical simulation techniques, such as the method of moments implemented in the FEKO software package, can produce realistic scattered electric fields of an organismal model, a Honeybee worker (i.e. Apis Mellifera) in this case.
The backscattering cross sections are calculated for both the horizontal and vertical polarizations at multiple wavelengths and diverse viewing angles. In fact, this numerical technique can be still useful to generate a considerable data of radio scattering through a broad set of azimuth or elevation angles by eliminating the practical difficulties associated with laboratory measurements. Although the simulated scattering properties of the honeybee obtained through the FEKO method of moments agree with the past controlled measurements when the honeybee broadside-on to the incident wave polarized horizontally at 9.41 GHz, more direct laboratory measurements for quantifying radio wave scattering at different wavelengths, polarizations, and viewing angles are required to assess the validity of this numerical electromagnetic technique.

Such a numerical electromagnetic technique could be applied for airborne insects and have a significant impact on the field of radar entomology, for instance, the quantifying scattering wave properties of these insects can be used with other parameters (time of flight, altitude..etc) for developing a classification system to discriminate between species of flying insects.
