( 2 ) the causation that the caustic phenomena of electromagnetic wave propagation in two - dimension concave reflectors occurs and the types of singularities in caustic fields are investigated, and the conclusion that there are two types of singularities ( fold and cusp ) in caustic fields in two - dimension concave reflectors is obtained ; by symplectic geometrical method, formulations of computing wave fields in and far away from caustic fields in two - dimension concave reflectors are deduced, and the results are plotted in pictures. ( 3 ) the cause of the caustic phenomena of electromagnetic wave propagation in three - dimension concave reflectors and the types of singularities in caustic fields is discussed, and the conclusion that there are three main types of singularities ( fold, cusp and swallowtail ) in caustic fields in three - dimension concave reflectors is obtained ; by symplectic geometrical method, the formulae of computing wave fields in and far away from caustic fields in three - dimension concave reflectors are deduced. particularly, the wave fields in ellipsoid concave reflector are computed, and the results displayed in special sections are given

論文主要包括三個方面： （ 1 ）分析了凹面反射的焦散現象，給出了不同凹面反射的焦散圖； （ 2 ）分析了二維凹面反射波動場焦散現象產生的原因及焦散區奇性的種類，得出了二維凹面反射波動場焦散區奇性主要有折疊（ fold ）和尖點（ cusp ）兩種的結論，利用辛幾何方法構造了圓錐曲面反射波動場非焦散區和焦散區的通用計算公式，並給出了圓柱面、橢圓柱面及雙曲柱面反射的計算結果； （ 3 ）分析了三維凹面反射波動場焦散現象產生的原因及焦散區奇性的種類，得出了三維凹面反射波動場焦散區奇性主要有折疊（ fom 、尖點kusp和燕尾k ）三種的結論，提出了利用辛幾何方法計算三維凹面反射波動場非焦散區和焦散區的計算方法，並給出了三軸不等橢球體凹面反射波動場的計算結果剖面圖。
