absorber - filter the field through intensity attenuator R .

Calling Sequence

[FIELD_out]=absorber(FIELD_in,R)

Parameters

Description

compute the field through intensity attenuator with the coefficient of attenuation (R greater than 1) or amplification (R smaller than 1)

Examples

	m=1;
	nm=1e-9*m;
	mm=1e-3*m;

	lambda=550*nm;
	sizes=5*mm;
	R=0.005;

	in=begin(sizes,lambda);
	out=absorber(in,R);
