A wavelength of each electromagnetic wave in the reflection hindering layer is referred to as λ2 and 2π/λ2 is set as a phase constant β2. An amount of deviation between a phase of a reflected wave reflected on the front interface of the reflection hindering layer in the travel direction and a phase of a reflected wave reflected on the rear interface is referred to as a phase deviation amount β. Thickness L2 of the reflection hindering layer is set to β/β2."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electromagnetic wave transmissive cover","description":"An electromagnetic wave transmissive cover includes: a base made of a dielectric material and having transmissiveness to electromagnetic waves; and a reflection hindering layer laminated on at least o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11527822","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.
