Aplikasi Elektromagnetika

1-6Fajardhani - 2005

1. When wave propagation effects cannot be neglected

1-7Fajardhani - 2005

2. When radiation is involved

1-8Fajardhani - 2005

3. When detailed field distribution is required

1-9Fajardhani - 2005

• High frequency analog circuits - Frequency ~ 1GHz - 10GHz

- Bluetooth - WLAN

1-10Fajardhani - 2005

Propagation effects cannot be neglected when the signal path is

not much smaller than the wavelength (e.g. ~0.1 wavelength)

• High speed digital circuits- System Clock ~ 1GHz

1-11Fajardhani - 2005

• Inside the circuit, velocity of electromagnetic

wave ~ 2x108 m/s– If signal frequency f = 1GHz,wavelength λ = 2x108 / 1x109 =

0.2m

1-12Fajardhani - 2005

• Optical Communications

1-13Fajardhani - 2005

Radiation becomes efficient when the dimension of conductor larger than 0.1

wavelength

Antennas

1-14Fajardhani - 2005

• Electromagnetic interference and compatibility

1-15Fajardhani - 2005

Other applications : 

– Linear motor

1-16Fajardhani - 2005

– Computer

1-18Fajardhani - 2005

Magnetic Levitation

• Trains can magnetically fly over a roadbed with position sustained by some kind of control system

• Force can either be attractive or repulsive

1-19Fajardhani - 2005

James Clerk Maxwell

• Born in Edinburgh, Scotland in 1831

• Attended Edinburgh Academy, The University of Edinburgh, and Cambridge University

• Published by the young age of 14

1-20Fajardhani - 2005

More on Maxwell

• Maxwell differed from his contemporaries in the nineteenth century

• Faraday & Ampere contributed to Maxwell’s theories

• Much of his important work was accomplished between the ages of 29 and 35

1-21Fajardhani - 2005

Maxwell’s Contributions• Analysis of color perception• An explanation of Saturn’s rings• Analysis of the theory of fluids and solids• Helped father modern statistical mechanics and

the molecular theory of gases

• Theory of Electromagnetism – Maxwell’s equations

1-22Fajardhani - 2005

Maxwell’s Equations

• Gauss’s Law, no monopoles, Ampere’s Law and Faraday’s Law
