Python (missile) that of US FIM-92 Stinger (infrared homing and ultraviolet), with IRCCM (IR ECCM) ability to reduce background IR radiation to reduce the effectiveness of enemy flares. The Python-5 is currently the most capable air-to-air missile in Israel's inventory and one of the most advanced AAMs in the world. As a beyond-visual-range missile, it is capable of "lock-on after launch" (LOAL), and has full-sphere/all-direction (including rearward) attack ability. The missile features an advanced electro-optical infrared homing seeker which scans the target area for hostile aircraft, then locks-on for terminal chase. With a total of eighteen control surfaces and careful design, the
Negative refraction propagation direction of the light, thus the sign of "n" must be chosen to match the physical situation. The principal symptom of negative refraction is just that – light rays are refracted on the "same" side of the normal on entering the material, as indicated in the diagram, and by a suitably general form of Snell's law. Negative refraction Negative refraction is the name for an electromagnetic phenomenon where light rays are refracted at an interface in the reverse sense to that normally expected. Such an effect can be obtained using a metamaterial which has been designed to achieve a
