Resonator Definition and 68 Threads

If EM waves are pumped into a resonant cavity at it's resonant frequency will each incoming wave add it's energy to amplify the wave(s) in the cavity? I know that if you pulse a light source into a circular wave guide and you pulse the light source each time the light wave returns to it's...

Respected members, PLEASE help me in determining quality factor of a piezoelectric rectangular plate MEMS RESONATOR in COMSOL multiphysics.there is a need to define some 'damping'.where should i define that.. PLS HELP ME ITS URGENT thank you and best

The rms EM field within a cavity resonator, excited in a single resonant mode by a current probe of fixed rms amplitude, is known to rise linearly with time; eg. http://www.jpier.org/PIER/pier78/15.07090605.Wen.pdf", sections 5.2, 5.3, fig's. 6, 10. (Normally it is a fixed driving voltage...

Hi, I'm learning something on circuit QED, which has a part called transmission line resonator (TLR). It plays the role of a cavity. However, I don't get how it works that way. Can anyone give some help ? Thanks in advance !

how to calculate induced emf in split ring resonator SRR of Metamaterial. what are the values of inductance capacitance & resistance of SRR

Homework Statement what is the resonator of the trumpet? A resonator is the part that vibrates at the resonant frequency. Homework Equations --- The Attempt at a Solution my friend said it was the air inside the tube, but I thought it was the tubes. thanks

So I'm about to construct a TE102 microwave resonator from folded copper sheeting. I'm planning to fold a U shape and join it to the last side with silver solder. Is this going to work well? I'm planning on making good physical contact through accurate folding, and then securing the pieces...

If my resonator is shorted at one end and has a partially transmitting grid at the other end is it correct to use S and T parameters to build a model of the device? I ask this as the first few sentences of the Wikipedia article on S-parameters states that a matched load should be placed at...

If we have a resonator composed of 2 partially transmitting mirrors/grids and we excite the resonator from one end, say the left side then on the right we expect to get the characterstic transmission comb and on the left the inverse (1-Transmission) reflection curve. Whats giving me a...

I am measuring the reflected power of a resonator for potential wireless applications. I'm pulsing the resonator with a 10.64GHz (resonate freq) pulsed waveform (10ns pulse width, 200ns period). Use an oscilloscope, it's easy to see the reflected pulse - with a maximum voltage just after the...

Homework Statement Prove that the quality factor of a rectangular cavity resonator which is filled with a lossy dielectric but has perfectly conducting walls, is given by Q = \frac{1}{\tan\delta} where \tan\delta is the loss tangent, i.e. the ratio of the imaginary part of the dielectric...

I am trying to find the impedance of a resonator, but I am not quite sure where to begin. The resonator contains three LCL circuits which are then connected to a large capacitor. Should I calculate the impedance of each element in the resonator or should I use Kirchhoff's Laws to analyze the...

when reading about the main differences between crystal resonators, oscillators and filters there's not much difference in operation, except that filters seem to have the crystal resonators and capacitors and resistors, And resonators seem to oscillate when the proper frequency is applied, And...

Homework Statement Self-Reproducing Rays in a symmetric Resonator. Consider a symmetric resonator using two concave mirrors of radii R separated by a distance d=3|R|/2. After how many round trips through the resonator will a ray retrace its path? Homework Equations The Attempt at...

Hey all, I'm trying to brainstorm a way to get a sound resonator (the order of hundreds of Hz) to create a voltage. I'm not exactly sure what the resonator should be constructed of... any ideas?

What type of circuit should one set up in order to induce chaotic outputs? My current research is pointing me towards a diode resonator circuit (resistor, inductor, diode in series) any ideas on that model or improvements from other research?

We've had a couple of exercises on lasers, and there's two I had some problems with: 1. He-Ne-laser Given A He-Ne laser with a 'base wavelength' (might be a bad translation of terminology, for which I apologize) lambda= 632.8 nm; Level width delta(nu) = 1500 MHz ; Allowed deviation...

NEMS Resonator I need a hint to help with my homework. The question: "A Si-Based NEMS resonator has dimensions length=150nm, width=5nm and thickness=5nm and an effective spring constant of 100Nm^-1 and natural frequency of vibration of 250MHz" I am looking for an equation linking the...
