Abstract
Active optical and microwave elements with periodic structures, located in the near radiation zone: sensor technologies transfer
Incoming article date: 28.09.2016The paper discusses the active microwave elements with periodic structures, located in the near radiation zone, that are based on optical technology transfer by analogy with controlled electro-layered structures. Among the considered: microwave antenna with controllable operating wavelength and radiation pattern width and its analog - selective multilayer dielectric mirror. Results and analysis of the main methods of modeling of microwave antenna and its periodic structure are discussed. Obtained characteristics of antennas in their experimental implementation are presented. The basic technology of antennas manufacturing and influence of their periodic structures manufacturing quality to accurately reflect the operating wavelength and the width of the pattern to the desired value are defined. Applications of antennas designed as shapers of the probing radiation in sensor and medical applications are shown. In particular, we discuss the creation of dielectric permittivity sensors and microwave treatment systems with controllable wavelength.
