waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface waves can occur at the interface between dielectric and con-ductive media or between two dielectrics satisfying appropriate boundary conditions. Air–salt water or glass–metal interfaces support electromagnetic surface waves. Here we focus on electromagnetic waves at the interface between common dielectrics and noble metals‚ such as air or glass and silver or gold‚ respectively. We will characterize these waves by their distinctive

Microwave Oven Who invented the Microwave oven Percy Spencer invented the first microwave oven after World War II from radar technology developed during the war. Named the "Radarange"‚ it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was first introduced byTappan in 1955‚ but these units were still too large and expensive for general home use. The countertop microwave oven was first introduced in 1967 by the Amana Corporation‚ which was acquired in

If one of the plates is removed‚ find the force acting on the same particle. 3. The plates of a parallel plate system are charged up to 100V. A 4mm thickness dielectric slab is inserted between the plates. Then to maintain the same potential difference‚ the distance between the systems plates are increased by 2mm. find the dielectric constant. 4. A point charge placed at any point on the axis of an electric dipole at some large distance experiences a force F. Find the force acting on the point

Machining processes ECM Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.[1] Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles‚ intricate contours or cavities in hardened exotic metals‚ such as titanium aluminised‚ Inconel‚ Waspalloy‚ and high nickel
