Abstract

An analytical expression for the time-dependent angular intensity at a specularly and diffusely reflecting surface of a semi-infinite medium is determined by the multiple collision formulation. The ratio of the net currents exiting the medium with and without reflection is then evaluated.

Riassunto

In questo lavoro viene risolta analiticamente, per mezzo del metodo delle collisioni multiple, l'equazione del trasporto per l'intensità angolare di radiazione alla superficie libera di un mezzo semi-infinito nel caso dipendente dal tempo e in presenza di riflessione sia speculare ehe diffusa sulla superficie stessa. Viene poi calcolato esplicitamente, per diversi valori delle riflettività speculare e diffusa, il rapporte tra la corrente netta esistente e quella ehe si avrebbe in assenza di riflessione.
