Microstrip Antenna using different feed techniques and study the effect of antenna dimensions Length (L)‚ Width (W) and substrate parameters relative Dielectric constant (εr)‚ substrate thickness on Radiation parameters of Band width. Low dielectric constant substrates are generally preferred for maximum radiation. The conducting patch can take any shape but rectangular and circular configurations are the most commonly used configuration. Other configurations are complex to analyze and require heavy numerical

Electromagnetic waves or radiation [pic] The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. This diagram shows a plane linearly polarized EMR wave propagating from left to right. The electric field is

Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

something about the wavelengths that make up a particular type of radiation (i.e.‚ the spectrum of radiation)‚ one could use an object such as simple diffraction parallel-slit grating in the form of a spectrometer. For example‚ molecules‚ atoms‚ and nuclei typically radiate or scatter radiation that corresponds to discrete frequencies and hence discrete wavelengths‚ λ. Knowing the spectrum (the intensity and wavelengths) of these radiations can tell us a lot about the molecule‚ atom‚ and nucleus under

nuclear chemistry with medicine is the form of radiation. There are types of methods used to apply radiation to the human body to outline some they will be medical imaging (X rays) and radiation therapy which are in the emphasis of nuclear medicine. Also nuclear chemistry has some other methods that deals with nuclear medicine called analytic methods which are using radioactive isotopes for biological tracers and using isotopes for dilution. Radiation can have beneficial and harmful effects towards

Electromagnetic radiation (EM radiation or EMR) is a form of radiant energy‚ propagating through space via photon wave particles. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one another‚ perpendicular to each other and perpendicular to the direction of energy and wave propagation

A lot of cancers do not have specific or noticeable signs. Therefore‚ prevention and correct screenings for cancer are of the greatest relevance. A lot of cancer screenings are normally age-specific. A primary care physician must suggest the correct screenings for cancer during yearly check-ups. There are several risk factors that are known to have an effect on and increase the associated risk of cancer. Healthcare experts advised that individuals take steps to manage their risk by making necessary

dangerous. They emit a type of radiation called radio frequency (RF) that has been shown to damage genetic material in blood cells‚ which can cause cancer. Radio frequency energy is a form of electromagnetic radiation. Electromagnetic radiation are categorized into two type: ionizing and non-ionizing. Ionizing radiation are found in x-rays‚ cosmic rays‚ and radon. Non-ionizing radiations are found in radio frequency and extremely low-frequency or power frequency. Ionizing radiation increase the risk of cancer
