Isibane se-FOG sangaphambili sisibane sentloko yemoto eyenzelwe ukuqaqamba nge-sharript beam. I-Beam ihlala yenzelwe ukuba ibe nendawo ebukhali enqunqiweyo ngaphezulu, kwaye ukukhanya kwangempela kudla ngokuphakathi kwaye kujolise emhlabeni kwi-angle ye-able. Ngenxa yoko, izibane ze-FOG zithi inqomo endleleni, ukuthumela ukukhanya kwendlela kwaye kukhanyisa indlela endaweni yenkungu. Isikhundla kunye nokuqhelaniswa nezibane zenkungu zinokuthelekiswa kwaye ziphiliswe nge-beam ephezulu kunye nezibane eziphantsi zokutyhila ngokuthe ngqo kwezi zixhobo zibonakala zizodwa zezi. Zombini izikhanyiso eziphakamileyo neziphantsi ezinama-appight zijolise kwii-angles ezinzulu, zibavumela ukuba bakhanyisele indlela ekude nemoto. Ngokwahlukileyo, ii-angles ezibi zisetyenziswa zizibane zenkungu zithetha ukuba zikhanyisele kuphela umhlaba phambi kwesithuthi. Oku kukuqinisekisa ububanzi bomngxunya wangaphambili.
