TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

KATHMANDU UNIVERSITY SCHOOL OF ENGINEERING Department of Electrical & Electronics Engineering LAB REPORT- III Reciprocity Theorem of Antenna (Tx and Rx pattern is same) By: Sudip Shrestha (41020) To: Manya Gautam Nov 21‚ 2010 Theory: 1. Reciprocity theorem: Many antenna properties are the same for both transmitting and receiving. It is often easier to calculate the gain of a transmitting antenna than the collecting area of a receiving antenna‚ and it is often easier

Electromagnetic spectrum is just a name for the range of ALL possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. The spectrum extends from below the low frequencies used for modern radio‚ to gamma radiation at the short-wavelength (or high-frequency) end‚ therefore covering wavelength for thousands of

MEN 510 Energy Conversion Assignment 2 Proton Therapy Presented to: Dr. Walid Assaf By: Farid Akiki 20082191 Semester: Fall 2012 Proton Therapy Proton therapy (also called proton beam therapy) is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle that is part of an atom‚ the basic unit of all chemical elements‚ such as hydrogen or oxygen. At high energy‚ protons can destroy cancer cells. Proton therapy

Waves Assignment Microwave Ovens Microwave ovens‚ or microwaves‚ are kitchen appliances which use microwave radiation to cook‚ heat or defrost food. Properties of a microwave: Microwaves are electromagnetic waves with wavelengths longer than those of Terahertz (THz) wavelengths‚ but relatively short for radio waves. Microwaves have wavelengths approximately in the range of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz). The word microwave generally refers to "alternating current signals with

CHAPTER -2 SADDLE ANTENNA 2.1 NOVEL UWB ANTENNA DESIGN CONCEPT Saddle antenna is a unique kind of flared antenna. This Ultra Wide Band antenna is based on using of two smoothly shaped flares of a simple geometrical structure – the saddle. The first flare‚ larger in size‚ serves as an antenna base‚ reflector and one of the radiator arms. The second flare‚ smaller in size‚ operates as the other arm of the radiator. An apparent idea is exploited in this design that an “ideal”
