    How to uninstall the programs in Linux?

    Hi, What kind of Linux are you using? The uninstallation depends on that too. If it is redhat/fedora/mandrake that has rpm packages, then from the command prompt a) check for the packages that you installed This will give you the exact name of the installed package. b) Uninstall that...

    microwave antenna design

    Hi, You have to consider the following design criteria for designing any of the antenna systems... a) Frequency range you are looking for. b) Transmitter power. c) Input impedance you are looking at. d) Gain of the antenna.. which gives you the distance... e) Directivity.... omni or...

    Sierpinski gasket fractal dimension design.

    Ananth, In that case, the Sierpinski gasket's base structure must be designed to resonate at 0.8GHz. The rest of the bands can be obtained by iterations/fractal growth. There is a design methodology for getting the triangle resonant at 0.8GHz. Refer Antenna texts like Antenna Theory by...

    FEM Vs MoM -- a discussion

    fem compared to mom planar FEM and MoM are the two major numerical techniques that todays EM Modeling rely on. I know that the time taken by both of these numerical techniques is high & consumes considerable memory as well. By and large, the results produced by FEM are much better when compared...

    Why do the satellite use high frequency ?

    Rautio -- Let me understand your above statement. Generally higher the frequency, lesser the wavelength. That is why AM being lower in frequency can travel longer distance whereas FM (high frequency) decays at a faster pace and can cover only a shorter distance. If we transmit AM & FM with the...

    paper presentation plzzzzzz

    Thats simple.. first pick the area you want... then search for the emerging technology in that area... collect data and present..Think this forum and google will be of great use for data collection. First decide the area in which you want to present..that's very important

    !? magnetic vector potential meaning

    Magnetic vector potential describes the "surface current radiation". It is a vector as it follows the direction of the current at any point in space. In any metal structure, the scattering field is due to a) electric vector potential(caused by surface free charge radiation) and...

    Is it necessary to match an antenna to free space impedance?

    Re: Matching Which impedance of the antenna you want to be 377Ω? At the input or at the surface/edge from where the waves actually radiate into free space?? If you do at the input, then you have to design the circuit's output impedance to be 377Ω. Even if you use a cable in between then it...

    Give me advice on selecting parts for RFID system

    Re: NEED HELP AND FAST! Hmm... UHF can go for longer range as the principle of operation is similar to that of radar. HF can go upto 1 meter but again depends on your system and the antenna gains. coming to the anti-collision in RFID... reader can service ONLY one tag at a time. Still the...

    A Fundamental Electromagnetics Question

    How can U have both zero?? I couldn't understand. The material should be either magnetic or eletric. It cannot be neither. Is there some material that exist with εr and µr as zeros??
