Hybrid rectangular heating applicators

摘要

A rectangular microwave applicator operating at a predetermined frequency and comprising a microwave enclosure forming a cavity having first and second transverse dimensions and a longitudinal dimension n the direction of propagation of microwave energy, wherein said dimensions are such that a main power-transferring Teym₁n mode with a long vertical wavelength is enhanced, and a significant amplitude of a complementary Teym₂n mode is created, wherein m₁, m₂ and n are positive odd integers and m₂ and n are both less or equal to m_1-2.
