## RCS of an Aircraft/Wing

I have not used hfss to this industrial level before, but if you are looking for somewhere to stat, I would definitely suggest importing a CAD model and characterizing your materials afterwards. This is not trivial, but I think as an aero engineer you'll be far more equipped to make a very impressive CAD model and import it into hfss and just assig

## Can we calculate RCS of an FSS structure using Floquet port

Hi to all; My question is that, Can we calculate the rcs of an FSS design in hfss by using the Floquet port? I have been told by some one that you should use incident plan wave to excite the unit cell of FSS and for that also change the solution setup in hfss. Is there any way to calculate the rcs using Floquet ports (...)

## HFSS Monostatic / Normal Bistatic RCS

Help please! I am simulating radar cross sections in hfss but I am a bit confused. It seems in theory that monostatic rcs and Bistatic rcs at theta=0, phi=0 with the same excitation should be the same. When for example, I simulate a 1 cm radius conducting sphere at 10 GHz I get -34.25 dB for Monostatic and -27.76 dB for bistatic at (...)

## RCS of a infinite flat metal plate using HFSS 11

Hi All, I'm using hfss 11 to simulate a infinite flat metal plate. I've created a unit cell, defined master slave boundaries and floquet ports. I parametised the theta scan angle.

## How to quantify "far-field" property in my HFSS mo

Standardly, hfss has the function of calculating rcs for an antenna or 3D object scattering. But my model is actually not exactly a 3D problem. I use periodic boundaries in the z-direction of my computational domain (surrounded by PMLs in x-y plane). I'd like to calculate the "rcs" for the "far-field" in some plane perpendicular to the z (...)

## Back RCS of Pa-tch on Grounded Dielectric Slab--IE3D vs HFSS

I recently used IE3D 11.15 to compute the back scattering rcs for a square conductor sitting on top of an infinite dielectric slab with a finite ground conductor (also a square).

## Which is the best simulator for RCS calculation

You can use many of the standard antenna tools to compute rcs. hfss, FEKO, and IE3D are examples of commercially available tools that support plane wave sources and rcs calculation. Even NEC can compute scattering for problems that can be appropriately modeled using wires and wire grids.
