We study the conditions for the formation and transformation of the Bessel plasmon-polariton field in a dielectric-metal structure excited by a Bessel light beam with arbitrary polarization. The effect of the metal layer thickness on the resulting plasmon field structure is investigated. The formation of Bessel plasmonpolaritons in a scheme consisting of a conical axicon with its base in contact with a silver layer of defined thickness is simulated.

Изучаются условия формирования и преобразования поля плазмон-поляритонов Бесселя в структуре диэлектрик-металл, возбуждаемой световым пучком Бесселя с произвольной поляризацией. Исследовано влияние толщины металлического слоя на результирующую структуру плазмонного поля. Моделируется формирование плазмон-поляритонов Бесселя в схеме, состоящей из конического аксикона, основание которого контактирует со слоем серебра определенной толщины.
