Kenneth S. Cole, Robert H. Cole · 1941
This 1941 foundational study by Cole established the mathematical framework for understanding how electromagnetic fields interact with different materials, including biological tissues.

This work became the scientific basis for measuring how EMF penetrates and affects living tissue.
C. F. Wagner, G. D. McCann, Edward Beck · 1941
This 1941 engineering study examined lightning strikes and electrical currents, measuring how lightning creates multiple electrical discharges and the wave patterns of these currents. Researchers found clear differences between direct lightning strikes and the electrical currents they produce in lightning arresters (protective devices).
John MacLeod, Robert S. Hotchkiss · 1941
This 1941 study examined how fever affects sperm counts in men, building on animal research showing that elevated testicular temperature damages sperm production. Researchers tracked sperm counts at various intervals after men experienced high body temperatures from fever treatment. The study confirmed that heat exposure significantly reduces male fertility, providing the first human evidence of temperature's impact on sperm production.

This 1940 study by Hasche examined how short wave radiofrequency radiation affects biological tissue in both human and animal subjects. The research represents one of the earliest scientific investigations into RF energy's biological effects, conducted during the early development of radio technology. This foundational work helped establish the field of bioelectromagnetics research.
HERBERT J. JOHNSON · 1940
This 1940 study compared how transplanted tumors responded to heat generated by short radio waves, testing both tumors grown in living animals versus laboratory conditions. Researchers used thermocouples to measure tissue heating and examine whether radio wave-induced thermal effects affected tumor sensitivity differently in these two environments.
Liebesny P · 1938
This 1938 research examined athermic short wave therapy, an early form of radiofrequency medical treatment that used electromagnetic fields without generating significant heat in body tissues.

This represents some of the earliest documented medical use of radiofrequency electromagnetic fields.
FRANK DICKENS, STANLEY F. EVANS, HANS WEIL-MALHERBE · 1937
This 1937 study examined whether short radio waves could treat tumors in live animals. Researchers found that radio waves only affected tumors when they generated enough heat to raise tissue temperature, with no special anti-cancer properties beyond thermal effects. The study concluded that radio wave therapy offered no advantages over established treatments like surgery or X-rays.
