Struct Metamaterial 

pub struct Metamaterial {
    pub name: String,
    pub eps_r_real: f64,
    pub eps_r_imag: f64,
    pub mu_r_real: f64,
    pub mu_r_imag: f64,
    pub freq: f64,
}

Frequency-dispersive metamaterial described by scalar Drude-Lorentz parameters at a single operating frequency.

Fields

name: String

Label.

eps_r_real: f64

Real part of relative permittivity ε’_r.

eps_r_imag: f64

Imaginary part of relative permittivity ε’’_r (loss).

mu_r_real: f64

Real part of relative permeability μ’_r.

mu_r_imag: f64

Imaginary part of relative permeability μ’’_r (loss).

freq: f64

Operating frequency [Hz].

Implementations

impl Metamaterial

pub fn classify(&self) -> MetamaterialClass

Classify the metamaterial based on ε and μ signs.

pub fn refractive_index(&self) -> f64

Refractive index n = √(ε μ). Negative for DNG media.

Uses the convention that the imaginary part is negative for lossy DNG.

pub fn group_velocity_approx(&self) -> f64

Group velocity v_g = c / (n + ω dn/dω). Here we return -C0/n for ideal DNG as a qualitative indicator.

Trait Implementations

impl Clone for Metamaterial

fn clone(&self) -> Metamaterial

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metamaterial

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
