朱國瑞教授從的專長為離子體物理,研究重點為電子迴旋脈射(Electron Cyclotron Maser, ECM)。ECM係靜磁場中迴旋的電子,基於相對論效應所產生的受激輻射(stimulated emission)現象。ECM輻射將電磁波的頻段及功率推進到前所未有的新境界,在電磁波頻譜的毫米及次毫米波段,佔有獨特的地位。ECM輻射於核融合加熱、先進雷達、粒子加速、太空探測、材料處理、物性偵測及頻譜學等應用,發揮了高度的實用價值,同時輻射機制本身也具有高度的研究價值,為應用物理學門帶來了許多新的研究題材。
朱教授的主要學術工作為: (1)以相對論動力方程式,深入探討電子迴旋脈射到中的數學及物理問題,發現迴旋不穩定模式中,快、慢波之間的競爭關係,澄清了一個長久以來懸而未決的迴旋波激發機制問題; (2)發展非線性迴旋速調放大理論,完成一個功率超越state-of-the-art百倍的30 MW, 10 GHz 迴旋速調放大器設計,後於馬利蘭大學獲得實驗印證,CERN正委託工業界研製成品,擬應用於下一代加速器的研發; (3))發明並研究成功Ka頻段迴旋行波放大器,於頻寬、功率、增益及效率四個指標上,均超越屹立三十餘年的國際記錄,提供了開發新一代遠距離,高解析度雷達系統的關鍵技術,美國學術及工業界正進行後續研發,擬應用於太空站雷達性能的提昇; (4)配合國家大型計畫,將研究成果付諸實用,研製成功同步加速器的高頻系統及高功率毫米波發射器,啟動國內的微波管工業,並大幅提升國防雷達系統的自主能力。
朱教授曾獲得國科會傑出研究獎、教育部首屆國家講座、教育部理科學術獎、總統科學獎傑、行政院傑出科技榮譽獎、IEEE 學會Plasma Science and Application Award及英國物理學會K J Button Medal and Prize,膺選為中華民國物理學會、美國物理學會、IEEE等學會之Fellow、及中央研究院院士。
