Gandhi OP · 1975
This 1975 study by Gandhi examined how microwave radiation is absorbed by human bodies and found that absorption peaks when the body's longest dimension equals about 0.4 times the wavelength of the radiation. The research revealed that the neck region experiences maximum power absorption, creating a resonance effect that increases absorption 3-4 times beyond what the body's physical size would predict.
James C. Lin, Chuan-Lin Wu, C. K. Lam · 1975
This 1975 study examined how electromagnetic pulses penetrate human and animal head models using mathematical modeling. Researchers found that electromagnetic pulses change shape as they enter the head, with the transmitted pulse being proportional to the rate of change of the original pulse. The peak effects occurred at the surface where the pulse first enters the head.

This early scientific attention to microwave health effects helped establish the foundation for modern EMF safety discussions.
Henry S. Ho · 1975
This 1975 study calculated how microwave energy distributes through a human thigh using mathematical modeling. Researchers simulated an irregularly-shaped thigh cross-section to understand how microwaves penetrate and spread through biological tissue.

Taflove A, Brodwin M E · 1975
This 1975 study used computer modeling to calculate electromagnetic fields and heating patterns inside the human eye when exposed to microwave radiation at 750 MHz and 1.5 GHz frequencies.

This 1974 research by Kholodov examined how electromagnetic fields affect the human brain and nervous system. The study highlighted that while we're constantly surrounded by electromagnetic radiation from external sources, we understand very little about how these fields interact with our body's own electrical systems.

Naval Medical Research Institute scientists proposed a new theory for why humans can hear pulsed microwave energy. They found that microwave pulses hitting head tissue create rapid heating and thermal expansion of tissue water, producing acoustic pressure waves that reach the ear through bone conduction. This challenges previous theories about how microwave radiation interacts with human hearing.

Researchers used computer models to calculate how microwave radiation is absorbed by the human skull at different frequencies. They found that a realistic multilayered skull model showed peak absorption at 2.1 GHz, which doesn't occur in simplified models, suggesting microwave oven leakage at 2.45 GHz may pose greater health risks than previously recognized.
