Abstract:
In this paper we propose the efficient planar selective electrodynamic system, composing of two coupled parts: receiving - made in the form of two similar rectangular open apodized periodic metal microresonance structures for the matching with the environment, and matching - made in the form of two similar waveguide lines with linearly varying width - for the optimal coupling with the input waveguide transmission line. Results of calculations with using the software package - HFSS (High Frequency Structure Simulator), providing simulation of the system and allowed to optimize the basic parameters of its three-dimensional structure for specific applications at the working resonance frequency of 1.82 THz are adduced. It is shown that such planar quasi-optical system has a higher efficiency of radiation energy conversion to the electronic flux energy (up to 86.4 %) and can be realized by a well developed integral technology in the industry. The carried out analysis of proposed planar apodized metal open microresonator structure for selective reception of radiation in the terahertz range confirms perspectives of using it to create devices and appliances for the present the feebly practically mastered range of electromagnetic waves. Thus planar components are practically more claimed due to their low cost, compactness and constructive combination with other circuit components performed in the form of the total printed circuit board.
