Scattering of Solar Flux by Panel Grooves
نویسنده
چکیده
The amount of scattering of solar radiation by grooves machined into the surfaces of the MMA antenna panels is estimated. Circular cross-section grooves are found to be much more effective than triangular grooves since they scatter over a wider range of angles. The groove pitch should be comparable to or smaller than the wavelength at the highest operating frequency, or about 100300 μm, and have a radius of ~0.7 mm.

Scattering of Solar Flux by Panel Grooves: Update
Fine grooves machined into the surface panels of an antenna help to scatter solar radiation. In an earlier memo it was concluded that a circular profile for the grooves was superior to a triangular. After correcting some errors in that note the triangular grooves appear to be more effective. The corrected formulation and some additional comments are presented here.
