## Matlab - RCS calculation surf function

On the Mathworks page I have found the following: surf(Z,C) plots the height of Z, a single-valued function defined over a geometrically rectangular grid, and uses matrix C, assumed to be the same size as Z, to color the surface. See Coloring Mesh and Surface Plots for information on defining C. And this is the page where the

## What is the grid size in layout for 250nm technology tsmc?

What is the grid size in layout for 250nm technology tsmc?

## CADSTAR 16.0 PCB layout drawing

Oh it is that simple. If you want a specific size circle I find it easiest to set my grid to 1/2 that size, draw the circle then change the grid down to enable it to be moved into location. Although with CADSTAR 16 you can rmb and enter coordinates and radius for a circle.

## Standard grid size for analog layout

Hi, Can anyone please tell me the standard grid size (mm) for a typical analog layout. Thanks & Regards.

## Fine snap feature on Proteus Professional 7

Go to technology tab>set grid snap There you can find the different grid settings

## Online impedance estimation

The difficulty in the estimation of Zg using is that the voltage source of the grid (Vs) is immeasurable. . VPCC = Ig*Zg +Vs The difficulty is turning off the switch for all the grid current, as Ig is used everywhere, not just your location. IMHO comments. It is a classical ESR method except the grid distributes th

## Why big cell size leads to wrong results?

Simulating 5 and 10GHz patch in Sonnet Lite. If i set cell size to 0.1mm all looks nice. But with 0.2mm i get strange spikes up to S11 = +15dBm! Even without feeding, when setting port directly on patch. Here is example in attachment: S11 curve for 0.1x0.1 mm grid, and for 0.2x0.2 mm grid with strange spike to +15dBm. Why it happens?

## sentaurus meshing strategy

Hi, The grid size determines how accurate your simulations results will be either for process extracted results or for electrical extracted results. There is an obvious trade off between increasing the mesh to improve accuracy versus simulation run time. It is recommended that you define the mesh tightly in areas of importance i.e. 1nm to 2nm gr

## Reflectivity vs Object Size

Then why corner reflector called so? Or a satellite dish made of metal grid. its called a corner reflector cuz it has a corner angle bend in the reflector, commonly 60 or 90 degrees the vertical height of the reflector is usually a bit larger than the length of the radiating element. The length of the sid

## basic concepts of physical verifications

That is vast field and is difficult to summarize all here. In brief, In DRC, all drawing rule related to size and separations are checked. These rules are defined in design rule manual (DRM) of the process you are using. off grid violation also comes under DRC checks. In LVS, we check the connectivity of layout with respect to schemtic. It has no

## SAR values and Grid in SEMCAD

Hi all, I am using the SEMCAD software to calculate SAR values for a model of a dipole and a flat phantom. The size of the dipole and the phantom as well as electrical parameters are as in IEC 62209-2. However, I could not obtain the SAR values as the reference in IEC 62209-2. If I increase the grid resolution in SEMCAD, I got a higher SAR va

## Matlab code for beam propagation with variable ,rectangular grid spacing

Hi, I would like to request somebody to help me in the following Matlab problem: I want to propagate a converging optical beam down its focus. I have started with a 1024 x 1024 number of grid points across the beam ( an uniform circle of white colour inside a background square of black colour------the size of the square is 6.5 mm x 6.5 mm a

## About the grid size and track width of polygon pours for 2.4GHz

HI, I recently draw a PCB for a 2.4GHz RF circuit.I have draw solid copper pours at the beginning,regarding to sheilding interference signal,i decide to draw hatech pours.I have a problem here.i don't konw the exact grid size and track width of ploygon pours for 2.4GHz.can you help me ？thx.

## Neat Schematic software in Electronic Magazines

The neatness of schematics depends on how you set up your schematic software, how you draw your symbols, grid spacings, relative text size, design flow etc etc, it has nothing to do with the package.

## PWM problem with a PIC18F4550

I found just changing from T1CON = 0b00001001; to T1CON = 0b00000001; will make the pwm work in this simple case. But in my LED grid clock, even T1CON = 0b00000001; or just this alone TMR1ON = 1; will make it stop to work. Any thoughts?

## Guidelines for Schematic & Symbols Design (Projects & Libraries)

Hello Folks, I am begining a new project and I would like to use common Schematic design guidelines (which must not to be the same as PCB Layout guidelines). So, I wonder if you could help me with some advice. Anyway, to begin the discussion, I have some questions already. For instance: 1) Which is the best grid size when you design Sch

## Varying node density not changing ber

Hi, I have a square grid network with eight nodes on the square (in corners and centre of sides) and one node at the centre. Having considered centre node as destination, am trying to get bit error rate with fixed poisson traffic at all nodes and fixed packet size. Bit errors are found with respect to nearest neighbors of centre node as tranmsit

## fixe vacuum dimension and mesh grid in cst

You can create a box with the desired vacuum size. Then you have to unselect under mesh properties the part "Consider for bouding box" in all objects. And in the mesh properties of the vacuum box you could set the mesh grid.

## edge SMA size question

they said the distance is 0.1" between center pin and outside pin Yes, I have never seen a SMA (or SMB, MCX ...) PCB connector with a different pin grid. You can download SMA catalogs and datasheets from major manufacturers and check yourself.

## Altium Designer Resizing PCB

I'm not sure what version of AD you are using, but in Summer 09 you can do: Design -> Board Shape -> Move Board Vertices This has worked well for me (just set the grid to something fairly large)
