M-Glossary

Magnetron:  Magnetron is essentially a tube utilizing electrical and magnetic currents for creating an intense heat output. The electromagnetic energy thus created has speeds equivalent to the speed of light.Microrobotics: Microrobotics is a futuristic field of studying robotics at the micron scale. Microrobotics applications are used in medicine (non-invasive surgery), cell biology et al.  Microrobotics can be broadly classified into two main categories. Manipulating micron sized objects using larger robots and fabricating tiny intelligent robotic systems from micron sized parts.

Millimeter Wave: Millimeter Wave Technology is a technology to transmit signals at comparatively high frequencies.  Millimeter Wave Technology is increasingly making its mark commercially. In imaging applications at Airports and high security threat areas,   Millimeter Wave technology can bounce non-harmful electromagnetic waves off the passenger’s body and producing a black and white three-dimensional image. Other than security applications the technology also finds increasing use in communications and traffic-control systems.

Microprocessor: A microprocessor aka CPU (central processing unit) is the brain of the computer whether a desktop or Laptop.  It is a complete computation engine fabricated on a on a single integrated circuit or chip.MEMS Technology: Micro-Electro-Mechanical Systems (MEMS) is an emerging technology for making microscopic machines. Using microfabrication technology, MEMS integrates actuators, mechanical elements, sensors and electronics on a common silicon substrate. MEMS is a groundbreaking technology which makes possible the realization of a complete systems-on-a-chip by fusion of silicon-based microelectronics with micromachining technology.MOSFET: MOSFET or Metal-Oxide-Semiconductor Field-Effect-Transistor technology is today one of the most popular semiconductor techniques. It is considered a key element in integrated circuit technology. The MOSFET devices can be split into various categories such as N-channel, P-channel, Depletion mode and Enhancement mode MOSFET. In most of the modern devices the transition from bipolar transistors to MOSFETs is complete. A typical MOSFET contains an n-(p-) doped silicon substrate along with two, highly p-(n-) doped contacts- drain and a source. The channel region in between is covered by the gate oxide, a thin insulating layer. The gate-oxide remains in touch with the gate electrode.MC-CDMA: Multi Carrier Code Division Multiple Access or MCC-DMA is a relatively new concept to be used in telecommunication systems. MC-CDMA is a combination of OFDM (orthogonal frequency division multiplexing) and CDMA (code division multiple access) both radio access techniques.Metadata: Metadata essentially provides a description about other data. For example in a webpage the information about the content is provided by metadata. Web pages include metadata by way of Meta tags. Search engines use this data while adding pages of websites to their search indices.
