📡 Wave Propagation 101: How Signals Travel, Penetrate, and Target
“If you want to fight RF-based targeting, you need to understand how the wave behaves.”
Everything we deal with — from Wi-Fi to mind-reading signals to directed energy — relies on wave propagation. Whether it’s a surveillance system bouncing signals off your walls, or a microwave weapon targeting deep tissue, it all starts with how electromagnetic (EM) waves move through space and materials.
Let’s break down what wave propagation is, and how it’s used (and abused).
🌊 What Is Wave Propagation?
Wave propagation is the movement of energy through a medium — like air, water, or even solid objects — in the form of a wave.
In RF (radio frequency), wave propagation describes how EM signals travel from one point to another.
🔍 Key Concepts
Term
Meaning
Frequency (f)
How fast the wave oscillates (Hz)
Wavelength (λ)
The distance between peaks of the wave
Amplitude
The strength or power of the wave
Phase
Where the wave is in its cycle
Attenuation
Loss of signal strength over distance
Reflection
Bounce off surfaces (walls, ceilings)
Refraction
Bending through different materials
Diffraction
Bending around obstacles
Penetration
Ability to go through materials (like drywall or skin)
📡 Types of Propagation
1. Line-of-Sight (LOS)
Travels in a straight path
Requires no obstructions
Used in lasers, microwaves, mmWave weapons
2. Ground Wave
Follows the curvature of the Earth
Used in low-frequency systems (VLF, LF)
Can travel hundreds of miles at low frequencies
3. Sky Wave (Ionospheric Bounce)
Bounces off the ionosphere
Used in HF (high-frequency) communication and possibly some covert radar systems
Can reach global distances
4. Penetrative Near-Field
Used by neuroweapons and through-wall radar
Short distance but deep tissue or object penetration
Frequencies: UHF, L-band, sometimes ELF/VLF
Can resonate with the human body
🧠 Application: Targeting Technology
Application
Uses Wave Propagation For
🛰 Surveillance
Tracking via bounced RF signals (UWB radar, 5G sensing)
🔊 Voice-to-skull (V2K)
Focused microwave/ultrasound beams to skull
🧬 Neuromodulation
High absorption into tissue using IR or RF carriers
🏠 Through-wall radar
Detect motion, respiration, presence via UWB waves
💣 Directed Energy Weapons
Focused, high-intensity EM to heat or disrupt cells
🧪 Propagation Through Materials
Material
Effect on Waves
Air
Minimal attenuation
Concrete
Moderate attenuation at low GHz
Water / Tissue
Strong absorption in microwave and IR bands
Metal
Total reflection or absorption (depending on thickness)
Drywall / Wood
Moderate penetration, depending on frequency
📌 Lower frequencies (VLF, UHF) penetrate deeper but carry less data. Higher frequencies (GHz+) are more precise but attenuate fast.
🧠 Final Thought
Wave propagation isn’t just science — it’s strategy. It’s how modern weapons and surveillance systems reach you. But it’s also how we learn to detect, block, and respond.
🛡️ If they ride the wave, you need to master the wave.
