Homework Statement


I have a homework about microwave .I need to create a microwave ,a instrument can create a microwave, and I don't know how to do.
I 'm form China ,so my English isn't good.And I hope you can help me !thanks!

look up magnetron or klystron

but if I need it like a wall, how can I?Just like a line .The microwave will create from up to down,and it just to be a wall.we know a instrument could create a line-circle microwave,I need it to be a Cylindrical,it could full of a Cylindrical,just form the outside of Cylindrical,and on the anther side could fine the microwave which is form the first side.And all the microwave is Average.Can it be true?
 
I know English is not your first language, but I really can't understand any of that. Can you explain more clearly? If not, post in Chinese and I'll try to translate.

ok
就是说,我想要实现一个设备,可以在垂直面上辐射微波,就像是在一个杆上的每个微面元上所辐射的微波是等效的。等同于一个圆柱体的某一条母线上辐射出的微波,在该母线上的单位元上微波的频率是一致的。这个装置要怎么设计?我知道微波是全方位传播的,但是怎么才能实现使微波充满一个圆柱体,使里面的微波辐射的几乎处处相等呢?
 
##|\Psi|^2=\frac{1}{\sqrt{\pi b^2}}\exp(\frac{-(x-x_0)^2}{b^2}).## ##\braket{x}=\frac{1}{\sqrt{\pi b^2}}\int_{-\infty}^{\infty}dx\,x\exp(-\frac{(x-x_0)^2}{b^2}).## ##y=x-x_0 \quad x=y+x_0 \quad dy=dx.## The boundaries remain infinite, I believe. ##\frac{1}{\sqrt{\pi b^2}}\int_{-\infty}^{\infty}dy(y+x_0)\exp(\frac{-y^2}{b^2}).## ##\frac{2}{\sqrt{\pi b^2}}\int_0^{\infty}dy\,y\exp(\frac{-y^2}{b^2})+\frac{2x_0}{\sqrt{\pi b^2}}\int_0^{\infty}dy\,\exp(-\frac{y^2}{b^2}).## I then resolved the two...
Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
