Solution Overview

Problem

Existing technologies fail to effectively diminish or capture waveform energy, particularly in high-rise buildings where the distance between shield enclosures and earth is significant, and they do not provide non-inverted, non-reduced reflected waveforms or efficient absorption of electromagnetic energy across specified frequency ranges.

Innovation Solution

The use of prime polygon reflectors with absorptive media, which are designed with geometric shapes based on prime numbers and their square roots, causing multiple internal reflections and allowing waveform energy to pass through absorptive media multiple times, thereby increasing absorption effectiveness without requiring an electrical ground.

Solution Approach 1:

The invention divides the shielding function into multiple discrete reflective elements arranged in a geometric pattern, where each element contributes to the overall shielding effect through multiple internal reflections, eliminating the need for continuous grounding

Inventive Principle:

Solution Approach 2:

The patent introduces an intermediary geometric structure that mediates between the electromagnetic field and the ground, using controlled reflections to achieve shielding without direct electrical connection to earth

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

Solution Approach 1:

The geometric arrangement of reflective elements creates periodic internal reflections, forcing the waveform energy to pass through the absorptive media multiple times in a cyclic manner, significantly increasing total absorption

Inventive Principle:

Solution Approach 2:

The continuous reflective path within the geometric structure ensures that waveform energy remains trapped and continuously interacts with the absorptive media until sufficiently attenuated, maintaining useful absorption action throughout

Inventive Principle:

AI summary

Disclosed herein are various forms of prime polygon reflectors. In its various forms it is a device of predetermined geometric shape with aspects and scalable dimensions derived from a prime number and its mathematical square root. Geometric shapes based on the prime polygon have reflective surfaces that cause multiple internal reflections of incident waveform energy. In some forms the reflectors are truncated comprising arrayed truncated prime polygon reflectors. When used in conjunction with or absent absorptive media, coatings, or linings, they reject passage of electromagnetic energy within a band that varies with reflector size and can be used with or without a ground. Applications include but are not limited to acoustic, solar, and radar energy absorption, as well as passive barriers for reduction of electromagnetic radiation exposure, and bandwidth-tunable panels for architectural electromagnetic shielding.
