Struct ShieldingEffectiveness 

Source 
pub struct ShieldingEffectiveness {
    pub mu_r: f64,
    pub sigma: f64,
    pub thickness: f64,
}
Expand description

Electromagnetic shielding effectiveness of a conductive enclosure.

SE = R + A + M (dB) where R = reflection loss, A = absorption loss, M = re-reflection correction.

Fields§

§mu_r: f64

Shield material relative permeability μ_r.

§sigma: f64

Shield material conductivity σ [S/m].

§thickness: f64

Shield thickness d [m].
