I will typically pass out solutions in class.
Several students indicated they had trouble finding tables of integrals and derivitives to do their exam and hw problems. I have provided a scanned table for you. It probably has more integrals than you ever wanted -- about 600 of them!
Severl students indicated they wanted a formula sheet for the mid-term exam. This sheet covers chapters 1-3.
You have not had much exposture to two-port networks in your circuits classes; however, two-port and multi-port networks are often encountered in rf and microwave circuits. These are some basic notes on h-, y-, z-, g- and ABCD parameters.
Here are some basic formulas on using L-section impedance matching networks using a purely algebraic approach.
This is a nice set of basic e&m formulas.
This is a similar formula set for pulses on transmission lines.
Here is an e&m formula sheet from MIT's 6.013 class.
Smith charts: b/w and color from Sullivan at Dartmouth.
Everything you ever wanted to know about Smith Charts including some more charts which you can download.
This is a modified version of ARRAYPATGAIN (text, 8kB) which can display phase plots for both end and center phase references
This is a another modified version of ARRAYPATGAIN (text, 8kB) which can overlay field amplitude plots for arrays of isotropic and short dipole sources.
Several authors have begun putting extensive note sets and even complete textbooks on line. Some of these are quite useful.
This text provides a broad and applications-oriented introduction
to electromagnetic waves and antennas. Current interest in these areas
is driven by the growth in wireless and fiber-optic communications,
information technology, and materials science
The text is organized around three main topic areas:
* The propagation, reflection, and transmission of plane waves, and
the analysis and design of multilayer films.
* Waveguides, transmission lines, impedance matching, and S-parameters.
* Linear and aperture antennas, scalar and vector diffraction theory,
antenna array design, and coupled antennas.
The text emphasizes connections to other subjects.
The text makes extensive use of MATLAB. We have developed an "Electromagnetic Waves & Antennas" toolbox containing 130 MATLAB functions for carrying out all of the computations and simulation examples in the text. Code segments illustrating the usage of these functions are found throughout the book, and serve as a user manual.
This is an set of brief notes about electromagnetic waves beginning with a review of basic fields and covering electromagnetic waves, polarization, reflection and transmission, parallel plate waveguides, slab waveguides, rectangular and cylindrical waveguides, and resonators. It is accompanied by an excellent set of Java Applets which can be manipulated to better understand the material.
This is an set of notes about transmission lines. It is accompanied by an excellent set of Java Applets which can be manipulated to better understand the material.
There appears to be a reasonable amount of software out there for computer solution of electromagnetic fields.These are links to some useful programs:
MATLAB programs for various fields problems. This is for Kraus & Fleisch, Electromagnetics with Applications, 5th Edition, an excellent fields textbook.
MATLAB programs for various fields problems with an emphasis on transmission lines and antennas. This is for Electromagnetic Waves and Antennas by Sophocles J. Orfanidis as described above.
Poynting Software, Ltd. offers SuperNEC to students and faculty. This commercial electromagnetic and antenna simulation program has a MATLAB interface and uses the Method of Moments to compute fields for complex structures. A scaled down version is available for course usage but requires a free site license.
NEC (Numerical Electromagnetic Code) has its source code available and has been compiled for a number of computer including Windows and Mac machines. NEC, which was developed at Lawrence Livermore Labs in 1981, uses the Method of Moments to compute the field patterns for complex radiating structutres. Since this was developed by the government it is free.
