Microwaves are generally considered to be a specific part of the wide radio
frequency spectrum. The band from 300 MHz to 30 GHz is typically considered
to be “microwaves,” for example by the Institute of Electrical end
Electronics Engineers (IEEE), although many of us prefer to set the lower
limit somewhat higher—perhaps at 1 or even 3 GHz. Above 30 GHz, the
term “millimeter waves” is used. High school physics suggests that we are
talking about wavelengths ranging from about 30 cm down to 10 mm...
This book is based on recent research work conducted by the authors dealing with the design
and development of active and passive microwave components, integrated circuits and
systems. It is divided into seven parts. In the first part comprising the first two chapters,
alternative concepts and equations for multiport network analysis and characterization are
provided. A thru-only de-embedding technique for accurate on-wafer characterization is
Novel generation wireless system is a packet switched wireless system with wide area
coverage and high throughput. It is designed to be cost effective and to provide high spectral
efficiency . The 4th wireless uses Orthogonal Frequency Division Multiplexing, Ultra Wide
Radio Band and millimeter wireless and smart antenna. Highly directive, planar UWB
antennas are gaining more and more attention, as required in many novel and important
This book deal with the modern developing of microwave and millimeter wave technologies.
The first chapter is aimed at describing the evolution of technological processes for the design
of passive functions in millimetre-wave frequency range. From the results HR SOI seems to
be a good candidate in the coming year to address both low cost and low power mass market
CMOS digital and RF/ MMW applications.
Today, the development and use of microwave (3-30 GHz) and millimeter wave (30-300 GHz)
band is being actively promoted. Microwave has been used extensively since the Second World
War when the sources were based on vacuum devices. Microwaves are presently playing a
vital role in RADAR, land and satellite based communication and also have wide civilian and
defence applications. Two typical areas of application of millimeter-wave are information
communication and remote sensing.
Carbon nanotubes are one of the most intriguing new materials with extraordinary properties being discovered in the last decade. The unique structure of carbon nanotubes provides nanotubes with extraordinary mechanical and electrical properties. The outstanding properties that these materials possess have opened new interesting researches areas in nanoscience and nanotechnology. Although nanotubes are very promising in a wide variety of fields, application of individual nanotubes for large scale production has been limited....
Surface Acoustic Wave (SAW) devices are widely used in multitude of device concepts mainly
in Micro Electro Mechanical Systems (MEMS) and communication electronics. As such,
SAW based micro-sensors, actuators and communication electronic devices are well known
applications of SAW technology. Due to their solid state design and fabrication compatible
with other modern technologies such as Microwave Integrated Circuits (MIC), MEMS, (Charge
Coupled Devices) CCD and integrated optic devices, SAW based sensors are considered to be
Infrared radiation is a type of electronmagnetic radiation (a wave with electricity) . The wave is longer than light which humans can see and shorter than microwaves. • The name means "below red". The word "Infrared" is from the Latin infra ("below") and red, which has the longest wave for light.
Research on nanoparticles, including synthesis, characterization of the structural,
chemical and physical properties, assembly into 1-, 2- and 3-dimensional
architectures extending over several lengths scales and with hierarchical construction
principles, and application in various fields of technology, represents
a fundamental cornerstone of nanoscience and nanotechnology.
