L plot and its strength, convergence at fr, peak Q holds good. Non linearity observed at Q plot only. If data is wrong others will not holds good. Without using smooth option in MATLAB, another way to measure smooth Q??
Hi,
I have s2p files for computing Y11. while converting s to y parameters using formula in matlab, wide variation in Re(Y11) is observed. how to fix the issue?. Alternatively i have tried with inbuilt function also, but it doesnot support large data.
How to extract resistance of FR4 substrate from given surface resistivitity or volume resistivity?
(Thickness is 1.6mm, surface resistivitity = 4*10^6 and volume resistivity = 2*10^9.)
Yes .. you are correct. The feed is not properly united to the spiral properly and hence the material assignment and solved in check up doesnt work.. even though they are explicitly shown
hi,
I have designed spiral coil over fr4 substrate using driven terminal. while simulating the coil, the following error occurs.
" Port 1 does not have a solved inside material on either side..". I checked with solved inside box and the port also matches with terminals. but still the error...
Hi,
i have designed a circular spiral coil using equation based curve in HFSS. while sweeping along path if the circle radius is 0.1mm the coil sweeps correctly. but when the circle radius is increased to 0.2mm, curve get diminishes leaving circle alone. how to fix this issue?
Is there any...
what is the laptop configuration required for analysing wpt characteristics between two 3d spiral inductors (mm range)? Do dedicated graphics memory required for HFSS simulation? cpu clock speed, ram memory ? Do hfss run in MAC o.s?
How to calculate self capacitance of circular spiral coil without substrate? Can i use medhursts formula for single layer coil "c = 0.29L+0.41R+1.94(R^3/L)^0.5"?
For various values of wire radius, pitch and internal radius (given that fixed outer diameter) have been simulated using HFSS. It shows that least value of Q is 8 n maximum is 467267. Is this maximum value permissible?

For maximum Q, series resistance should be minimum. For...
How to choose optimal wire width of spiral coil to attain high q factor? There are formula to calculate optimal turns n pitch. Is it by trail n error to choose wire width?
S(1,1) converges around 10MHZ. Delta S has been set to 0.01 and maximum passes are set to 8. Message manager shows that adaptive passes didnot converge. When passes are set to 12 it shows Matrix solver exception: out of memory. I am using 16GB RAM.Maximum RAM limit has been set to 15,000MB in...
