This booklet is the 1st entire and complete description of the fashionable actual concept of Diffraction (PTD) in response to the concept that of ordinary part waves (EEWs). the idea is tested with the instance of the diffraction of acoustic and electromagnetic waves at completely reflecting gadgets. The derived analytic expressions sincerely clarify the actual constitution of the scattered box and describe intimately the entire mirrored and diffracted rays and beams, in addition to the fields within the area of caustics and foci. Shadow radiation, a brand new primary component to the sector, is brought and confirmed to comprise 1/2 the complete scattered power.
__________Книга представляет собой первое полное и всестороннее описание современной физической теории дифракции, основанной на понятии элементарных краевых волн. Теория показана на примере дифракции акустических и электромагнитных волн на идеально отражающих предметах. Полученные аналитические выражения чётко объясняют физическую структуру рассеянного поля и подробно описывают все отражённые и дифрагированные лучи и пучки, а также поля в окрестности каустиков и фокусов. Вводится теневое излучение - новая фундаментальная составляющая поля и показывается, что она содержит половину всей рассеянной энергии.
