Description
  • Paper deals with complex permittivity measurement of biological tissues. Application of a waveguide probe for this measurement is shown. A nondestructive and noninvasive method based on reflection coefficient measurement - probe is attaching the material under test, is used. New types of the probes are under investigation - the section of waveguide with H cross-section, the section of waveguide with the rectangular cross-section and with shorted walls, the section of waveguide with inserted dielectric wedge and finally the section of waveguide filled with liquid dielectric. Properties of these prototypes are studied in frequency range from 300 kHz to 3 GHz. FDTD method is utilized for the numerical modeling and simulation of the reflection coefficient. Results indicate that the most interesting and suitable is the solution with removable dielectric.

  • Článek se zabývá měřením komplexní permitivity biologických tkání a aplikací vlnovodné sondy v měření. Pro měření komplexní permitivity se používá nedestruktivní a neinvazivní metoda založená na měření činitele odrazu. Jsou uvažovány nové typy sond pro měřicí účely: úsek vlnovodu s průřezem %22H%22, úsek obdélníkového vlnovodu se zkratovanými stěnami, úsek obdélníkového vlnovodu s vloženým dielektrickým klínem a úsek obdélníkového vlnovodu vyplněný tekutým dielektrikem. Vlastnosti těchto prototypů jsou studovány v kmitočtovém pásmu od 300 kHz do 3 GHz. FDTD metoda je použita pro modelování a k simulacím činitele odrazu. Výsledky ukazují, že nejvíce zajímavá a použitelná je sonda s výměnným dielektrikem. (cs)
