Field descriptors and deterministic helpers (phasor convention e^{+jωt}).

->field clj

(->field {:keys [type frequency-hz amplitude orientation phase-deg polarization
                 meta amplitude-distribution phase-distribution]
          :or {type :electric
               frequency-hz 0.0
               amplitude 0.0
               orientation [0.0 0.0 1.0]
               phase-deg 0.0}})

Normalise a field descriptor. Keys (keywords) are namespaced with :field/. Supports amplitude/phase distributions for stochastic modelling.

power-density clj

(power-density field material)

Time-averaged Poynting vector magnitude (W/m^2) for a plane wave. Returns {:value .. :units :w-per-m2 :valid? bool :flags #{..} :impedance eta}.

sample-field clj

(sample-field field)

(sample-field field rng)

Draw a stochastic sample from a field distribution.

superpose clj

(superpose fields)

Phasor sum of co-linear harmonic fields. Returns a new field map; frequency/type are derived from the first element.
