ICSD : Inorganic Crystal Structure Database
dSpace : Calculates the inter-planar spacings, angles, and twin-related reflections of any crystal structure.
XRD : Calculates the structure factors and full x-ray diffraction pattern for any crystal (beta version – not all elements supported).
Gamma : Calculates the Gamma function which can be used in the solution of Bessel
Calculates the relative permittivity of a resonator tested in Hakki-Coleman
(or Courtney) parallel plates, given the resonant frequency and geometry.
Calculates the relative permittivity of a post resonator.
Recommended reading before running the above programmes.
Calculates the Bessel functions involved in these equations.
