Electromagnetic Waves & Antennas Toolbox

Companion Software

Description

A toolbox of functions to accompany the author's online book on "Electromagnetic Waves & Antennas". The book may be downloaded from the web page

http://www.ece.rutgers.edu/~orfanidi/ewa

The toolbox includes functions for the design and analysis of multilayer film structures, antireflection coatings, polarizers, omnidirectional mirrors, narrow-band transmission filters, birefringent multilayer films and giant birefringent optics; impedance matching methods, quarter-wavelength multisection Chebyshev transformers, stub matching, and L, Pi and T-section reactive matching networks; analysis of transmission lines and waveguides; S-parameters, Smith charts, stability and gain circles, noise figure circles, and microwave amplifier design; computation of directivities and patterns of linear and aperture antennas; horn design; computation of diffraction integrals and knife-edge diffraction coefficients; antenna array design methods for sector and narrow beams; numerical methods for the Hallen and Pocklington integral equations; computation of self and mutual antenna impedances; coupled antennas; various types of azimuthal and polar gain plots; and several movies showing the propagation of pulses on terminated transmission lines and on cascaded lines, reflections from reactive terminations, fault location by TDR, crosstalk signals on coupled lines, and time-evolution of the field radiated by a Hertzian dipole antenna.

Usage examples are found throughout the above text. The functions were developed with R11.1, but they work with R13.

• MATLAB release: MATLAB 5.3.1 (R11.1)

This is simply the best reference to do antennas with MATLAB!

[Henrique Silva]

Comprehensive and very well detailed.
An amazing amount of work.

Regarding the user review dated 2005-03-16, I would like to point out that I did not write that review! The reviewer mistakenly used my name instead of his/her own name in submitting the review.

[Zaid Muhi-Eldeen]

Excellent work includes alot of very helpful mfiles.

Excellent Work ... espicially in antenna ...
I know it is easy to do myself with some operations but , it's better to write some other useful functions like : Field Pattern , Calculate HPBW and Antenna impedance Nomogramme .

[Mohamed LASHAB]

Well done I am very satisfied, I hope if there is some software for reflector antennas, the field I am interrested in, many thanks.

Matlab tells me that the variable 'th' is undefined in line 55 of file multidiel2.m; sure enough, 'th' has not been defined in terms of anything else. Has anyone else run into this?

[Paul Ciszek]

1) I did not mean to give this package a rating of "2"; is there anyway to remove my previous review?

2) There is a more recent version of the MATLAB code available on the book's website, http://www.ece.rutgers.edu/~orfanidi/ewa/ It corrects the problem I mentioned in the previous review.

i need the dipole block in my simulation

thanks you

This is really amzaing work. Worth the highest ranking.

With regard to file chebarray. It is my understanding that the central element excitation will always be the largest with odd number of elements. Your program doesn't show this when element size becomes > 11. Could you provide an explanation?
