A conductive plate or sheet is fixed to an inside surface of the second plate. An electrical circuit connects the first plate to the conductive plate or sheet. The replicate matching material and the conductive plate or sheet generate an opposite polarization pattern carried by the electrical circuit that is based on a polarization pattern of smokeless gunpowder according to a spatial gradient of the smokeless gunpowder local electric field distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic selective polarization matching for remote detection of smokeless gunpowder","description":"An analog matching filter includes a first plate, a second plate coupled with the first plate and separated from the first plate via a spacer, and a replicate matching material fixed to an inside surf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11300541","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
