Aim of study (acc. to author)
, 5 min on/10 min off for 8 h
Two R18 hollow rectangular
waveguides (131 mm x 65 mm x 425 mm) operating in TE10 mode were used with a removable short cut making them a resonating cavity. They were equipped with ventilation holes, a fan and several sensors. Data from all sensors ( field strength, air temperature, fan driving current) were collected every 10 s in a data logger also controlling the GSM frame unit and the RF switch. The whole setup with dimensions of approx. 50 x 25 x 45 cm³ was placed in a CO 2 incubator.
Six 35 mm
Petri dishes fixed in two holders were placed in each waveguide, and in the H-field maxima being separated by 106 mm. The amplified RF signal was connected to one of the waveguide cavities by a computer-controlled switch enabling a double-blind study design.
