Electromagnetics

INTRODUCTION.
o Electromagnetics = Electricity + Magnetics
o A great deal of modern technology depends
upon the advent electromagnetics waves.
o Radio, television, mobile phones and the
Internet rely on the transmission of radio
frequency EMR through air, space or fiber
optic cables.
o The lasers used to record and play DVDs
and audio CDs use light waves to write to
and read from the discs.
o Its breakthrough in medicine and
telecommunication application happens to
be the greatest achievement of all

ELECTROMAGNETICS IN MODERN MEDICINE
 Electromagnetics intervention in medicine has achieved a breakthrough in aspects where
conventional medicine failed such as:
 Detection of internal medical problems in the body such as broken bones and fractures
 Early detection of cancer
 Location and treatment of Cancer and Tumours
 Treatment of Hyperthermia
 Monitoring of Patients in coma or intensive care units
 Diagnosis and treatment of Epilepsy and Brain failure
 Electrocardiography and Electroencephalography

o A Magnetic Resonance Imaging
(MRI) machine
o A mobile X-ray Machine o A soft X-ray and
Mammography Machine
SOME ELECTROMAGNETICS EQUIPMENTS IN
MODERN MEDICINE

ELECTROENCEPHALOGRAPHY
 This is the most current electromagnetic advancement in
modern medicine
 It is the measure of electrical activity in the body through
the scalp which is used to detect issues such as:
• Brain failure
• Epileptic seizures
• Psychiatric syndromes
• Prognosis in patients who are in a state of coma

MEDICAL WIRELESS IMPLANTS
 it is a minute transmitting device to be planted inside the body of humans
 It helps in getting details of patient who are in coma or maybe, unable to talk
 it is used solely for transmitting current up-to date information of its carrier such
as
 Blood group
 Age and
 other required medical information

ELECTROMAGNETICS IN COMMUNICATION
 The discovery of electromagnetic waves has made Communication easier and less tedious
 Wireless communication has taken over in almost all available aspects
 Electromagnetic waves made it easier to send information over long distance through space
 Electromagnetic waves are used in the following aspects of telecommunication:
 Radio waves
 Amplitude and Frequency Modulation
 Radar Technology
 Microwave Communication
 Telemetry

A radio wave antenna for receiving
information from outer space
A Radar antenna for sending and
receiving information
A Base Transceiver Station equipment
used in encoding and decoding
information to be sent and received
SOME ELECTROMAGNETICS COMMUNICATIONS EQUIPMENTS
 Telecommunication equipments include antennas, satellite receivers and so on
 They are used to send and receive information through electromagnetic waves in
space

• Some antennas used for sending and receiving electromagnetic signals
• Telemetry; which is an automatic process of making measurements from a remote location and
transmitting those measurements to receiving equipment also utilizes these antennas.

• Electromagnetics has successfully made life easier in the area of modern medicine and communications due to its contribution
in aspects like:
• Satellite Communication
• TV and mobile Communication
• Wireless Communication
• Microwave Communication
• Bio-medical systems
• Radiation therapy
• Remote sensing radars
• Radio astronomy radars
• And many more
• Electromagnetics has therefore helped in increasing in life expectancy, easier communication, reduced mortality rate etc.
CONCLUSION

Faraday Maxwell Hertz
APPRECIATION
 Credits should be given to scientist such as Michael Faraday, James Clark Maxwell and
Heinreich Rudolf Hertz for their breakthrough researches in electromagnetics thus creating a
bedrock for modern medicine and communications
