electromagnetic propagationの例文

• From 1867 Hemendranath Thakur began conducting his first experiments into radio waves and electromagnetic propagations.
• Operation Highjump, from 1946-1947 was organized by electromagnetic propagation conditions in the area.
• Beam tracing has been successfully applied to the fields of acoustic modelling and electromagnetic propagation modelling.
• The software then solves a set of thermal equations across the boundaries and for electromagnetic propagation in a specified infrared waveband.
• Bown's work focused on electromagnetic propagation, particularly for radio broadcasting, ship-to-shore communication, aircraft radios, and intercontinental telephony.
• Eigenmode expansion is a rigorous technique to simulate electromagnetic propagation which relies on the decomposition of the electromagnetic fields into a basis set of local eigenmodes that exists in the cross section of the device.
• When transverse electromagnetic propagation occurs with a transmission line medium, the analogy for permittivity and permeability is ? = L, and ? = C . This analogy was developed with positive values for these parameters.
• The objective of the Expedition, outlined by President Franklin D . Roosevelt, was to establish two bases : East Base, in the vicinity of Charcot Island, and West Base, in the vicinity of electromagnetic propagation conditions in the area.
