    pub lambda_london_0: f64,
    pub xi0: f64,
}

Superconductor electromagnetic parameters.

Fields

tc: f64

Critical temperature Tc [K].

lambda_london_0: f64

London penetration depth λ_L at T = 0 [m].

xi0: f64

BCS coherence length ξ₀ [m].

Implementations

impl Superconductor

pub fn new(tc: f64, lambda_london_0: f64, xi0: f64) -> Self

Construct superconductor parameters.

pub fn ybco() -> Self

Typical parameters for YBCO (YBa₂Cu₃O₇).

pub fn niobium() -> Self

Typical parameters for niobium.

pub fn penetration_depth(&self, temp_k: f64) -> f64

Temperature-dependent London penetration depth [m] using the two-fluid model: λ(T) = λ_L(0) / √(1 − (T/Tc)⁴).

pub fn gl_parameter(&self, temp_k: f64) -> f64

Ginzburg-Landau parameter κ = λ / ξ.

κ > 1/√2 → type-II superconductor.

pub fn surface_resistance( &self, freq: f64, sigma_normal: f64, temp_k: f64, ) -> f64

Surface resistance Rs(f) [Ω] in the Mattis-Bardeen limit (low T, f << 2Δ/h): R_s ≈ μ₀² σ_n ω² λ³_L / 2.

pub fn is_superconducting(&self, temp_k: f64) -> bool

Whether the material is in the superconducting state at temp_k.

pub fn hc1_estimate(&self, temp_k: f64) -> f64

Lower critical field Hc1 estimate [A/m] (from London theory).
