the equation is true. For instance, if i have p(x) as undefined function such like a curve of square function or any other undefined curve. We can call the denominator and the numerator with another function like g(x).
For instance, if g(x)=tan(x) which equals to sin(x)/cos(x) but in my equation...
Hello Dears,
I would like to design a polarizer filter that can transmit a specific polarization of the electromagnetic waves, but I do not know:
how to design it ?
how can i choose the proper geometries?
Best Regards
thanks for your reply.
That means that the internet connections are not supported by the base stations of the cellular phone?
I do not understand this point. How can the length of the train be utilized?
Nowadays the internet connections in the trains trips are available and anybody can sign in and enjoy the time. The Wifi technology in the trains are connected to the network coverage of the base stations (BTS) of the cellular phones, but I noticed when I am in the train in rural regions where...
If I have a dispersive material with a complex permeability and permittivity and I want to know the possibility of hysteresis occurrence inside this material, how can I check for that or how to plot the hysteresis loop?
I desire to design a microwave filter using Chebyshev polynomials but I would like to use dispersive materials for the multilayer structure. In this case the parameter 'X' will be Complex
T1 (x) =x
T2 (x) =2x2 − 1
T3 (x) =4x3 − 3x
T4 (x) =8x4 − 8x2 + 1
T5 (x) =16x5 − 20x3 + 5x
did someone do...
Hello dears
I desire to find the original proof of this equation of the fractional bandwidth Radar absorber
I found it in a an open access paper and the reference of it was in " Radar Cross section Handbook, by G. Ruck, Chapter 8 " , but unfortunately, I do not have this book. I hope...
Hi, Thanks c_Mitra & CataM,
what I meant is clear in this eqaution :
Is the RHS equal to LHS of the equation ??
by the way, I do not have any infinite values in the measurements, but I can measure only in a specific bound of frequencies [w1,w2].

take in your account...
Thanks very much C_mitra. There are no problems with the integration in general but what I meant is how can I apply the same equation on a limited values of omega 'w' for example I need to integrate in the duration [w1,w2] instead of [0, inf.]. Is the integration will be the same in both...
If I have a general integral equation with a semi-bounded limits from zero to infinity and I want to apply this equation on some deterministic values. The integration in this case must be converted to a deterministic integral, but how?
for example, in the equation below, I want to find the...
Hello Dears
I would like to insert an external AC current on my design.
for example: if I have a dielectric substrate backed with a metal plate and on the top there is a microstrip TL, and I want to feed the TL with an external AC current instead of the waveguide port.
Does anybody has an...
Hello Dears
I use the kramers kronig (KK) relations to demonstrate the arbitrary values of the dielectric constant with the measured values, but in the derivation of KK relations, there is a Cauchy value P as shown below, but I dont know how to determine its value.
Is there anybody have an...
I need to simulate a microwave absorber using CST, but i want to illuminate the absorber using TEM wave instead of waveguide input port.
Is there anybody has an expertise how to input TEM wave using CST?
I desire to design a multi-layer of Salisbury screen, but when I choose the values of the resistive sheets for two or three layers, I do not get the required results for a Broadband of frequencies.
Is there any one has an experience with such a design of multi-layer and how he chose the values...
