Description
  • Pro konstrukci stíněných boxů, krytů a další aplikace je velmi důležité znát účinnost stínění plochých materiálů, jako například stínicích panelů, speciálních nátěrů, okenních fólií a dalších. Účínnost stínění je možné měřit ve volném prostoru nebo ve vlnovodu. Měření ve volném prostoru bylo provedeno v anténní bezodrazové komeře, která byla rozdělena stěnou s oknem, do kterého byly vkládány měřené materiály. Pro vlnovodová měření byla navržena a vyrobena vlnovodná měřicí linka pro měření velkých úrovní stínicí účinnosti tenkých vodivých materiálů ve frekvenčním pásmu 350 - 500 MHz. Pomocí obou metod byly změřeny stínicí účinnosti různých materiálů a výsledky byly porovnány. V závěru byly diskutovány výhody a nevýhody zmíněných metod měření. (cs)
  • Knowledge of shielding efficiency of plane materials like shielding panels, special paints, windows foils etc. is demanded for construction of shielded boxes, enclosures and for other applications. Shielding efficiency is possible to measure in free space or in waveguide. Measurement in free space was performed in divided anechoic chamber by wall with window there are placed measured materials. Waveguide measurement unit was specially designed and manufactured to measure the high level of shielding efficiency of thin conductive materials in the frequency band of about 400 MHz. The shielding efficiency of various materials was measured by means of both methods and the results were compared. At the end is discussion about advantages and disadvantage various methods.
