John Howard Dellinger

The Dellinger effect, or sometimes Mögel–Dellinger effect, is another name for a sudden ionospheric disturbance. The effect was discovered by John Howard Dellinger around 1935 and also described by the German physicist Hans Mögel (1900-1944) in 1930. The fadeouts are characterized by sudden onset and a recovery that takes minutes or hours

In recognition of his significant contributions to radio science, the International Union of Radio Science (URSI) established the John Howard Dellinger Gold Medal. This prestigious award honors individuals who have made outstanding achievements in the field of radio science.

For instance, in 2014, Professor Ryutaro Himeno received this medal for his advancements in electromagnetics.

By celebrating excellence through awards like the Dellinger Gold Medal, URSI inspires and motivates young scientists to pursue innovative research in radio science, fostering a culture of continuous learning and discovery
