Hello All,
I would like to convert a partial diff equation in time domain into frequency domain, however there is a term of the form:
Re(∇(E1.E2*) exp(j[ω][/0]t))
where E1 and E2 are the magnitudes of the electric field and [ω][/0] is the angular frequency.
Can someone please help me to...
Hi,
While writing the Fourier representation for the spring-mass system, we have the equation:
(-jωm+B-S/jω).U(jω)=F(jω) with F,U,m,B and S being the force, velocity,mass, damping coefficient and spring constant respectively.
From this equation, is it right to infer that :
1) Force lags the...
Hi All,
I am in need to calculate the ultrasound (20MHz) absorption of particles (polystyrene of size 15 microns) in water. I tried to search in the internet, but couldn't find any simple analytical expressions. Can someone please help me !
Thanks in advance!

Dear All,
Can someone give me an intuitive idea of the acoustic radiation force.
I have read from a paper that the acoustic radiation force generated by a standing acoustic wave is larger when the size of particle is smaller than the acoustic wavelength as compared to the case when size >...
Hello All,
I would like to know why do we multiply the complex conjugate of velocity (not just the velocity) with the complex pressure to obtain the complex acoustic intensity. Could someone please help me with this?
