In this simulation‚ you can input the temperature and observe the spectrum of the radiation emitted. a) The temperature of stars in the universe varies

1. i) • Antenna radiation pattern or antenna pattern is defined as “a mathematical function or a graphical representation of the radiation properties of the antenna as a function of space coordinates.” • The radiation pattern is determined in the far-field region and is represented as a function of the directional coordinates. • Radiation properties include power flux density‚ radiation intensity‚ field strength‚ directivity phase or polarization [pic]

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

Abstract Post-traumatic stress disorder is a common problem in for veterans returning from war all over the world. It can often be misdiagnosed as a traumatic brain injury or overlooked altogether because of the similarities in their symptoms. This article defines what post-traumatic stress disorder is as according to the Diagnostic Statistic Manual of Mental Disorders‚ its correlation with insomnia and nightmares‚ traumatic brain injuries and heart rate conditions‚ and it summarizes various treatment

hire someone to guard your favorite things? This research paper is going to talk about‚ how robots work. Terms that will be discussed in this paper will include Infrared (IR) light‚ electromagnetic radiation‚ electromagnetic spectrum‚ and sensors. Infrared radiation light is simply electromagnetic radiation with longer wavelengths (The American Heritage Student Science Dictionary 177). Infrared is usually called Infrared light‚ though it’s not visible to the human eyes (The American Heritage Student

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”

223.4 million U.S. citizens have experienced a traumatic event at least once in their lives. This is about 70% of adults in the USA. Today 31.1 million people are struggling with Post Traumatic Stress Disorder (PTSD) (Rosenthal). PTSD is defined as re-experiencing‚ avoidance‚ and arousal‚ due to a traumatic event. The symptoms are either long lasting or have a delayed onset (Oltmanns & Emery‚ 2012). A traumatic event that involves actual or threatened death or serious injury to self or others

often than we think because with out light we wouldent posibly be able to see color on any thing‚ or we wouldent have photosynthisis which sunlight is used for. The term spectrum refers to light in general or the whole range of electromagnetic radiation. The electromagnetic field was found in the 19th centurie. It was founded by James Clerk MAXWELL of Scotland and published in 1865. The field is described in two quantities the electric component E and the magnetic component B and both charge
