This book provides a broad and applications-oriented introduction to electromagnetic waves and antennas, with MATLAB examples. Current interest in these areas is driven by the growth in wireless and fiber-optic communications, information technology, and materials science. Communications, antenna, radar, and microwave engineers must deal with the generation, transmission, and reception of electromagnetic waves. Device engineers working on ever-smaller integrated circuits and at ever higher frequencies must take into account wave propagation effects at the chip and circuit-board levels. Communication and computer network engineers routinely use waveguiding systems, such as transmission lines and optical fibers. Novel recent developments in materials, such as photonic bandgap structures, omnidirectional dielectric mirrors, birefringent multilayer films, surface plasmons, negative-index metamaterials, slow and fast light, promise a revolution in the control and manipulation of light and other applications.

These are just some examples of topics discussed in this book. The book is organized around three main topic areas: • The propagation, reflection, and transmission of plane waves, and the analysis and design of multilayer films. • Waveguiding systems, including metallic, dielectric, and surface waveguides, transmission lines, impedance matching, and S-parameters.

This MATLAB function returns a Dolph-Chebyshev window object H of length 64 with relative sidelobe attenuation of 100 dB. Oct 03, 2008 MATLAB Based Toolbox for Phased Array Antenna Design and Analysis. A GUI program based on MATLAB which can answer. Dolph-Chebyshev array.

• Linear and aperture antennas, scalar and vector diffraction theory, plane-wave spectrum, Fourier optics, superdirectivity and superresolution concepts, antenna array design, numerical methods in antennas, and coupled antennas. The text emphasizes connections to other subjects. For example, the mathematical techniques for analyzing wave propagation in multilayer structures, multisegment transmission lines, and the design of multilayer optical filters are the same as those used in DSP, such as the lattice structures of linear prediction, the analysis and synthesis of speech, and geophysical signal processing. Similarly, antenna array design is related to the problem of spectral analysis of sinusoids and to digital filter design, and Butler beams are equivalent to the FFT.

Β = cos [ 1 / N cosh − 1 ( 10 α ) ] α determines the level of the sidelobe attenuation. The level of the sidelobe attenuation is equal to − 20 α.

For example, 100 dB of attenuation results from setting α = 5 The discrete-time Dolph-Chebyshev window is obtained by taking the inverse DFT of W ^ ( k ) and scaling the result to have a peak value of 1. Construction H = sigwin.chebwin returns a Dolph-Chebyshev window object H of length 64 with relative sidelobe attenuation of 100 dB.

H = sigwin.chebwin( Length) returns a Dolph-Chebyshev window object H of length Length with relative sidelobe attenuation of 100 dB. Length requires a positive integer. Entering a positive noninteger value for Length rounds the length to the nearest integer. A window length of 1 results in a window with a single value equal to 1. H = sigwin.chebwin( Length, SidelobeAtten) returns a Dolph-Chebyshev window object with relative sidelobe attenuation of atten_param dB.
