Interference

The Optics Interference program simulates a ripple tank by showing the intensity of waves produced by a point source. Adding multiple point sources creates easily observable interference patterns showing constructive and destructive interference. Users can add point sources, move them around, and... Platforms: Mac

The Young Two Slit Interference model simulates the interference pattern of light as it travels through two slits to a screen. This result was first described by Young who used the wave theory of light to describe the interference of light through two slits. The interference pattern is due to the... Platforms: Mac

The Diffraction and Interference Model: Single and Double Slits shows diffraction and interference patterns from a single slit, double sources and double slits. The user can change the source wavelength, slit width, separation and distance between slit and screen. The Diffraction and... Platforms: Mac

The Ejs Two Source Interference model displays the interference pattern on a screen due to two point sources. The simulation allows an arbitrarily superposition of the two sources and shows both the current intensity and running average of the intensity on the screen. The separation, phase... Platforms: Mac

The Thin Film Interference model investigates reflection and transmission of light through a thin film. The user can change the thickness and index of refraction of the thin film as well as the incident light wavelength. The Thin Film Interference Model was created using the Easy Java...

NOTE: Though I have uploaded this toolbox, I have no contribution in this work. Programming and research in this field has been done by students given belowKapil Gulati, Marcel Nassar, Aditya Chopra, Marcus DeYoung, Arvind Sujeeth, and Navid Aghasadeghi.It is composed of various functions used to... Platforms: Matlab

With this simulation, you can explore the ideas of interference and diffraction resulting from waves passing through a single opening (the single slit); waves being emitted with equal amplitude in all directions from two sources (the double source), and waves passing through two closely spaced...

Diffraction Lab Basic is a small, simple application specially designed to simulate wave interference and diffraction for a wide variety of diffracting elements. This version offers four diffraction elements: Square Array, Square aperture, 2-Point Source and 3-Point Source. Note: If you want... Platforms: Windows

This script performs an old-school demo effect, using sine wave interference patterns.It is entertaining for at least a few minutes. You can modify the frequency variable for different patterns. Requirements: - PyGame and Numeric modules Platforms: Windows, Mac, *nix, Python, BSD Solaris

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming. There are two different minimum... Platforms: Matlab

Walsh-Hadamard codes are mutually orthognal codes, thus when used in synchronous CDMA, the interference between users is zero. This programm generates Walsh-Hadamard codes and also checks the orthogonality. You can change the code length by changing value of "code_length" at the top of programan... Platforms: Matlab

Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a... Platforms: Windows, Windows 8, Windows 7, Windows Server

Nowadays, the use of so-called RNA interference is a common technique applied by molecular biologists to determine the function of the many genes in our genome.Unfortunately, the design of oligonucleotides, the building blocks for this technique, is a time-consuming and error-prone task. iRNAi...

A privacy and security aware mailing list manager, perfect for allowing closed groups to interact on the Internet without interference from outsiders and former insiders. Platforms: Windows, Mac, Linux

This is an old program (1.999) that I have written for understanding radiation patterns of antennas. Basically I was looking for the relationship between interference diagram (Fourier transform of ilumination, usually called Array Factor) and 3D radiation pattern of the Array. For that reason, it...

Use this to encode bit sequences with the duobinary signaling technique or the modified duobinary signaling technique.Duobinary signaling is a three level signaling scheme that uses intersymbol interference in a controlled way instead of trying to eliminate it. Platforms: Matlab

A collection of m-files aimed at learning and teaching about the principles of diffraction gratings. Some of these show a cross section of the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow...

This program simulates the interference pattern of two Gaussian beams. The simulation assumes that the beams are combined at a beam combiner which tilt angle (along x-direction) is arbitrary. The distance z from the position of minimal beam waist w0 to the beam combiner is, as well as w0,... Platforms: Matlab
