calcScat()

void LayeredSphereScat::calcScat

(

valtype

costheta

)

Calculate Scaterring matrix coefficients S1 and S2.

Parameters

[in]

costheta

\(cos(\theta)\) value.

set()

int LayeredSphereScat::set	(	const valtype	wl,
		const std::vector< std::complex< valtype > > &	eps,
		const std::vector< std::complex< valtype > > &	mu,
		const std::vector< valtype > &	r,
		const int	Nhrm = 20
	)

Set params before calculating.

Parameters

[in]	wl	wavelength
[in]	eps	array of particles' \(\varepsilon\) (last is inner, first is space)
[in]	mu	array of particles' \(\mu\) (last is inner, first is space)
[in]	r	array of particles' radii (first is the largest)
[in]	Nhrm	Number of harmonics, 20 if default (very large number results unstable)

Returns

-1 when sizes of eps,mu,r+1 are differ

1 success
