SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

propagation of their culture beyond the borders of their country has given the nation a new global identity; one that does not live in the shadow of its war-torn past. Hallyu has created a more positive image for the nation through its booming and trendsetting entertainment industry. The new image gained from the Hallyu Wave has also paved the way for smoother global transaction and relation.

Third-wave feminism has become synonymous with sex-positivity and the empowering nature of sexual activity. Sex-positivity has been defined as: “a celebration of sexuality as a positive aspect of life‚ with a broader definition of what sex means and what oppression and empowerment may imply in the context of sex.” This emergence of sexual positivity has created friction in the past‚ with ‘the feminist sex wars’ splitting feminists into liberal and radical camps. Despite this‚ the third-wave and sex-positive

Out of the darkness of the French defeat and capitulation of 1940 rose one of the greatest mass-resistance movements in history. Thousands of French patriots rose up‚ by themselves and in groups‚ and defied Nazi authority. They formed resistance movements that fought the Nazi occupation of France and the collaboration of the Vichy government. The French resistance was detrimental to the success of the Allies during World War II because they played a key role in the D-Day landings and were able to

Waves are mainly known for their way of transferring energy from one place to another without transferring any matter.Transverse and longitudinal are waves in which can be related to one another in some kind of way. A transverse wave is a wave in which vibrates perpendicular to the direction of the waves motion. As a transverse wave travels through a medium‚ the individual particles of the medium move perpendicular to the direction of the wave travel. They may occur in a string‚ in the surface of

have contributed to theories involving light. Of these‚ the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history‚ some physicists have argued that light behaves as a wave‚ such as Christiaan Huygens and others‚ such as Isaac Newton have proposed that light consists of particles (Wave-Particle Duality‚ March 2010). Today‚ as stated in the wave-particle duality‚ light is said to exhibit wave-like and particle-like properties. And still today‚ physicists

what is a wave? a wave is a disturbance which travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself. if a stone is dropped in a pond or swimming pool‚ ripples or waves are seen spreading on the surface of the water from the point where it was dropped. the water itself does not move in the direction of the ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical
