Although plants are supposed to restrict the performance of radio frequency transceiver systems (which is why the Wi-Fi signal becomes weaker in forests), they can also act as efficient biogenic elements, according to a study by an international team of scientists from the Moscow Institute of Physics and Technology (MFTI, for its acronym in Russian) and Tel Aviv University.<\/p>\n\n

The research, published in AIP Publishing, determined that plants can not only limit signals, but, due to their high concentration of water, they also act as elements of a dielectric resonant antenna that strengthens the electromagnetic field of objects.<\/p>\n\n

The study focused on investigating the capabilities of the cactus ‘Opuntia ficus-indica’ to serve as an efficient antenna device, which could be customized and contribute to various applications of WLAN and Wi-MAX wireless technologies covering ultra-wide frequency band. <\/p>\n\n

“At the beginning of the project we were faced with at least two tasks: to increase the harvest using the electrodynamic properties of plants and to use the studied electrodynamic characteristics to improve Wi-Fi connectivity in forest areas,” explained Dmitri Filonov, head of the laboratory at the Center for Photonics. and Two-Dimensional Materials from the MFTI, in a note published this week by Za Nauku magazine.<\/p>\n\n

“For this, it was necessary to understand which chains and bonds aligned the liquids in the capillaries of plants. A living system has different electrodynamic parameters. By studying them using microwave analysis, we monitor the dynamics of plant growth and can plan a careful competent and timely,” he added.<\/p>\n\n

“Studying the electromagnetic structure, we have solved the inverse problem: to use the system not for absorption purposes, but for radiation purposes, and at that moment an antenna emerged from a cactus. It has become a true test of all our hypotheses: we know how a plant is organized from the point of view of electrodynamics, how it can influence signals and how it can be used for radiation”, summarized the scientist.<\/p>\n\n

The high water content within the vegetation causes multiple resonances, which are reinforcing effects of the electromagnetic field of objects.<\/p>\n\n

The stems of the cactus studied by the researchers are almost 75-85% water, which made it possible to use the plant as a natural broadband omnidirectional antenna that operates in various Wi-Fi communication bands from 900 MHz to 7.7 GHz .<\/p>\n\n

The scientists mathematically described how the resonances of the stem are organized, connected a source to it, and the cactus began to generate electromagnetic radiation. The scientists explain that they chose ‘Opuntia ficus-indica’ for the research for the simple reason that it is very common in Israel. Also, it is often found in arid and desert areas, where establishing a wireless connection is a difficult task.<\/p>\n\n

Further research on plants as functional electromagnetic elements may help the development of environmentally friendly multifunctional devices and other green technologies, the paper’s authors concluded.<\/p>\n\n
