- Abstract:
- Use and application of the GTEM-cell, which is a transmission structure based on a TEM-cell approach, are described. The cell can be used for calibrating small antennas, for immunity and emission testing, and for biomedical experiments. It provides homogenous electromagnetic fields with TEM (transversal electromagnetic mode) distribution, similar to the free space. It has a shield to prevent radiation from the outside, which would interfere with our measurement. Plant Lemna minor has been exposed to the electric field similar to those of the cellular phones and the effect on the growth has been studied. The experiments included exposure to the frequencies of 400 MHz and 900 MHz with strength of electric field being 22 V/m. The time of exposure was 2 and 4 hours. The influence of AM (80%) 1 kHz sine modulation was also tested. Our investigations confirmed that electromagnetic field of frequencies produced by mobile phones or base stations can affect plant growth.
