Simulation and properties of the wide-band hybrid slow-wave system/Placiajuostes hibridines letinimo sistemos modeliavimas ir savybes

The meander slow-wave system with bended and formed lateral parts of meander electrodes is considered. The system has features of meander and helical systems and can be considered as the hybrid helical-meander-helical (HMH) system. The multiconductor line method and the CST Microwave Studio software system are used for simulation of the HMH system. Expressions for retardation factor and input impedance of the systems are derived using the multiconductor line method. The CST Microwave Studio software is used for calculation of characteristic impedance, retardation factor versus frequency and transfer function of the signal path containing meander and HMH systems. According to results of simulation, using formed meander electrodes, we can considerably increase characteristic impedance and ensure the wide-pass-band of the signal path.

[TEXT NOT REPRODUCIBLE IN ASCII.] Nagrinejama letinimo sistema, kurioje panaudoti meandriniai elektrodai su nukreiptomis ir suformuotomis periferinemis dalimis. Sistema turi meandrinems ir spiralinems sistemoms budingu bruozu ir gali buti laikoma spiraline-meandrine-spiraline (SMS) sistema. Sistemai modeliuoti ir jos charakteristikoms apskaiciuoti naudotas daugialaidziu liniju metodas ir kompanijos CST programu paketas Microwave Studio. Taikant daugialaidziu liniju metoda isvesta sistemos dispersine lygtis ir iejimo varzos israiska. Paketas Microwave Studio panaudotas sistemos banginei varzai, letinimo koeficiento dazninei charakteristikai ir signalinio trakto, kuriame panaudota meandrine sistema ir SMS sistema, amplitudes dazninems charakteristikoms apskaiciuoti. Parodyta, kad, naudojant SMS sistemas su nukreiptais ir suformuotais meandriniais elektrodais, galima gauti didele sistemos bangine varza ir placia praleidziamuju dazniu juosta.
