Abstract: The aim of this paper is to demonstrate how different substances, in this case fertilizers, behave when exposed to ultra-low frequency (ULF) waves using an active inertia sensor. Specifically, the goal of the experiment is to find the resonant frequencies of some fertilizers and, afterwards, to identify the common frequencies at which fertilizers containing similar molecular components are detected. The frequency range used in the experiment is between 5 to 8 kHz. Through studies conducted using an active inertia sensor emitting ULF and VLF frequencies, and various substances, it has been observed that substances sharing common molecular components can be detected by common frequencies. In this experiment, it will be demonstrated that this also holds true for a group of inorganic materials, such as fertilizers. The future goal is to develop a database that includes multiple substances and the frequencies at which they can be detected. Additionally, the use of fertilizers as simulants for military applications, including training, research, technology development, airport scanners, robotic bomb disposal units, and other security technologies, is highlighted. Furthermore, the advantages of using fertilizers as simulants, compared to actual explosive materials, are emphasized.
