    B Radio Frequency Acceleration in Particle Accelerators

    So, I've been really interested in Particle Physics since 6th grade when I did a project on particle accelerators. I understand most of it, except for one thing, the radio frequency cavities which are used for acceleration. I just want to ask, how do the Superconducting Radio Frequency Cavities...

    RF and MW receivers' sensitivity

    I'm currently working on a novel RF and MW sensor and I wanted to know whether there is a paper that shows the current very best receiver sensitivity for a range of wavelengths in the RF-MW range in dBm preferably so I can directly compare to my device.

    How to compute the location of the antenna when I rotate it?

    Hi group, I have a question regarding to detect the location of the antenna. I read this link: https://en.wikipedia.org/wiki/Plane_wave In the "Complex exponential form" part, the equation: U(r,t) = U0 * exp(j*(k.r - w*t) as the function of location and time U0 = A0 * exp(j*phi) : A0 and...

    How to calculate standard deviation from the delay?

    I am trying to calculate the unit vector and standard deviation of the signal. I hope everyone can give me ideas. Here is my scenario: I have 2 rx channels: - f is channel 1 with the length 1x256 complex, then FFT. - g is channel 2 with the length 1x256 complex, then FFT. - from f and g, I can...

    How to detect multipath?

    Hi everyone, I am a new engineer just work in the real industry, so I would like to collect more experience from the real project. I am working on the Multipath problem, but I've not done before in the University, and really do not know how to solve it. During the discussion from the...

    How to find a right RF module for a project?

    I am a product developer but not an electronics engineer. I am doing a cost analysis of a product idea for my company. The product will need something like this.... There will be two small portable devices (A and B) 1 meter apart (not in line of sight since A can be in pocket). Product A will...
