Code 1-20 of 20   






this program evaluates the impedance and phase velocity in the shielded microstrip transmission line. program helps to view the effect of dimension of shielding used.



Zfit(data)
Plots the impedance DATA which has to be a 3-columns wise matrix [FREQ, RealZEXP, ImagZEXP]. Impedance, admittance, capacitance and modulus representations in the complex plane are then pushbutton obtainable.

The others...



Show how to plot a Smith chart in Matlab. Show how to perform a 2 element match to 50 ohms termination using the Smith chart. Show that depending on the termination impedance that there is more than one combination of elements solving the problem.



Cilantro is an implementation (in Java) of "Object Algebra", a solution to the Impedance Problem. It connects object-oriented programs to relational databases. In Cilantro, queries are first-class objects and can be combined to create...



EIDORS (electrical impedance and diffuse optical tomography reconstruction software) provides software, algorithms and reference data for image reconstruction and modelling.



NeoDatis ODB is a very simple object oriented database that currently runs on the Java Platform and is being ported to .Net and Mono.

To avoid Impedance mismatch overhead between Object and Relational worlds, give a try to Neodatis ODB....



This code use the Matlab interface GUI to calculate the vertical antenna properties. The code requests two inputs. The inputs are:
- antenna length.
- antenna output impedance.
The program plot the antenna diagram and calculate:



A simple one-dimensional finite-difference time-domain (FDTD) electromagnetic routine that allows the user to specify arbitrary permittivity, permeability and conductivity profiles. Useful for helping students to visualize reflection,...



Optimisation for 4 variables using Genetic technique. Was designed to optimise surface impedance measurements



This package is a continues to be expanded. New examples include: VCO with user defined phase noise, impedance matching and filter design, interleaved ADC, clock multiplying delay lock loop, clock recovery for NRZ data. Further examples include:...



.m file to solve harmonic load flow for power systems (Matlab 2009).
Line Matrix is line impedance matrix.
load_power Matrix is P+jQ matrix of the loads.
source matrix is the complex value of the harmonic sources and they considered...



GUI to calculate and visualize the radiation pattern of ultrasound transducers.

linSmith is a Smith Charting program, mainly designed for educational use.

Features:
- Definition of multiple load impedances (at different frequencies)
- Addition of discrete (L, C, parallel and series LC, and transformer)...



Important Note:
This model could only be compatible with MATLAB 7(R14) and CCS 2.21. It might work for other versions of MATLAB & CCS but for that Sampling Rates & data types of various simulink blocks might have to be adjusted...



A collection of M-Files capable of drawing a standard colored smith chart including all the labels and scales which can be found on a standard smith chart. In addition it allows other lines and circles to be drawn on the standard chart.



The main features are:

Plot.
For each immitance types (Z, Y, C or M), the data can be plotted
in the complex plane, as well their real, imaginary parts or
their magnitude in function of the frequency (Log/Log).



horn.m is the main program which designs exponential and catenoidal horns. The user inputs the cutoff frequency (Hz) and the throat radius in (meters).

horn.m calculates the required length and shape constant of the horn to efficiently...
