Rf-based ai determination of materials by cycling through detection patterns for specific applications

A system comprising:

• a user interface configured to receive a selection of a target material from a user;
• a communication interface for accessing a material database associating each of a plurality of materials with one or more corresponding resonance frequencies, the plurality of materials including the target material;
• an RF transmitter configured to transmit into an environment an RF signal at the resonance frequency for the target material extracted from the material database;
• an RF receiver configured to receive a response signal from the environment;
• a processor configured to:
• analyze the response signal for resonance characteristics that indicate a presence of the target material in the environment;
• and
• if the presence of the target material is indicated:
• use a large language model (LLM) to determine a set of one or more related materials to the target material;
• for each related material of the set of one or more related materials:
• transmit into the environment an additional RF signal at the resonance frequency for the related material extracted from the material database;
• receive an additional response signal from the environment;
• and
• analyze the response signal for resonance characteristics that indicate a presence of the related material in the environment;
• and
• store an indication of the target material and each related material indicated to be within the environment.
