Description Usage Arguments Examples

View source: R/diffraction.line.R

Description

Return a diffraction line to be added to a plot, given a vector of in-plane wavenumbers (k)

Usage

1
diffraction.line(k, kgx, kgv, m, n, phi = 0, alpha = pi/2)

Arguments

k

in-plane wavenumbers.

kgx

the grating vector of the (phi=0) periodicity (2*pi/pitch)

kgv

the grating vector of the out-of-plane periodicity (2*pi/pitch)

m

in-plane scattering integer

n

out-of-plane scattering integer

phi

azimuthal angle away from kgx (phi=0 along kgx) in radians

alpha

angle between the two grating vectors in radians

{
    return(data.frame(k = k, omega = 3e+08 * (sqrt(((k * cos(phi) + 
        m * kgx - n * kgv * cos(alpha))^2) + ((k * sin(phi) - 
        n * kgv * sin(alpha))^2)))))
