Arthropods are divided into 4 groups: Myriapods : have 1 pair of antenna Long cylindrical or flat bodies with many legs. Crustaceans: have 2 pairs of antennas. Insects :have 1 pair of antenna 3 pair of legs Up to 2 pair of wings Arachnids: have no antennae or wings but 4 pairs of leg. Mollis (Molluscus) in Latin means

problem. Some people believe that the design of the iPhone’s antennas have a major flaw that is caused by bridging the antenna. This occurs when your hand or fingers covered the left side of the phone‚ causing the iPhone 4 to lose signal bars. I found this problem to not affect me‚ but it did affect some on my friend’s iPhones. The best way to resolve this problem was to purchase a case to prevent our bodies from coming into contact with the antenna. Although its design may cause network problems‚ it does

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

computer chip and an antenna‚ which the remote reader can scan and send to a database. It can be consider as a backbone of “internet of things”. There are many companies that already start using it to follow their inventory and other belongings of the institute. For example now Wall Mart required all suppliers to use RFID to track the products‚ and US military use it to follow the supplies around the globe. Each chip can get a unique serial number‚ which will be recognised by the antenna. And at the moment

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers
