This article is related to ADDA (light scattering simulator based on the discrete dipole approximation).

This articles shows the runtime arguement of ADDA in terms of the radius of the particle.

@ manual.pdf page 52

-eq_rad
Sets volume-equivalent radius of the particle in μm (§6.2), float. If default wavelength is
used, this option specifies the volume-equivalent size parameter. Cannot be used
together with -size . Size is defined by some shapes themselves, then this option can be
used to override the internal specification and scale the shape.
Default: determined by the value of –size or by -grid , -dpl , and –lambda .

Example

$ ./adda -shape bisphere 1.0 -m 1.5 0.005 -eq_rad 5

$ head -n 12 run22090_bisphere_g20_m1.5/log
