Radiant Wave technology was developed by Rakshata Chawla. It is initially employed as a weapon by the Guren Mk-II as the Radiant Wave Surger. It causes a chain reaction in Knightmare Frames which usually results in the parts expanding and eventually exploding, likely due to liquids present. With the Guren Flight-Enabled Version, it receives a new Armour Piercing Bombardment-type Radiation Wave unit which has the effect of internally damaging systems by spreading energy in a wide area to neutralize and disable enemy Knightmares; this weapon was used to great effect against the Tristan and the Mordred during Operation Pacific Ocean Ambush.The only known way of halting the chain reaction is to eject the damaged parts before other parts are affected. Initially, its range was suitable only for close-quarters combat, but it was soon upgraded to have a longer range (either taking the form of a straight beam or a wide-spread beam). It was further improved when the Guren Flight-Enabled Version was captured and its Radiant Wave Surger reversed engineered by the Camelot, enabling it to fire disk-shaped radiation beams and also project a radiation blade. Upon its recapture, the new weapon which was fitted to the Guren S.E.I.T.E.N. Eight Elements.
Eventually, this technology was developed into a shield system known as Radiant Wave Shielding because it naturally dissolved bullets and could even stop heavy weaponry like the VARIS, and was integrated into the Black Knights' Knightmares, including the Zangetsu and the Akatsuki Command Model Zikisan. Airships like the Ikaruga were also equipped with Radiant Wave Shielding; these airship-mounted versions were capable of stopping stronger weaponry and even falling rocks.
Radiant Wave technology was even incorporated into a missile warhead; these were usually used by the Akatsuki Command Model Zikisan, resulting in the same chain reaction effect upon contact wtih a Knightmare frame.
