Prof. Filippo Capolino ECE Dept. Fall 2006 Notes 2 ECE 2317 ECE 2317 Applied Electricity and Magnetism Applied Electricity and Magnetism Notes prepared by the EM group, University of Houston . (used by Dr. Jackson, spring 2006) Definition: no time variation. In terms of frequency, f = 0 [Hz] The electromagnetic field splits into two independent parts: Electrostatics: ( q , E ) Magnetostatics: ( I , B ) The static approximation is usually accurate for d << λ 0 ( d is the dimension of the circuit). Statics Statics Example: f = 60 [Hz] λ 0 = c / f Clearly, most circuits fall into the static-approximation category at 60 [Hz]! c = 2.99792458 × 10 8 [ m/s ] f = 60 [ Hz ] This gives: λ 0 = 4.9965 × 10 6 [m] = 4,996.5 [km] = 3,097.8 [miles] Statics (cont.) Statics (cont.) The following are special cases of electromagnetics at low frequency: • circuit theory (e.g, ECE 2300) • electronics • power engineering Examples of high-frequency systems that are not modeled by statics: • antennas • transmission lines • microwaves ECE 3317 Statics (cont.)
