Message-ID: <910D4DB7A594D111B047080009DFC614113C61@iwe-1.iwe.RWTH-Aachen.DE> Hi , I would like to introduce myself: I'm a phd-student working at the university of aachen / germany and my task is to simulate the behaviour of micromachined devices. Until now our group worked with ANSYS. Now we think about simulating a pair of micromachined transmitter and receiver. The transmitter and receiver look like helix antennas or flat coils and the distance between them is about twice the diameter. The diameter is about 2 cm, the working frequency is between 13 and 40 MHz. We want to calculate the transmission coefficient, the dynamic behaviour (transmitter and receiver change their position against each other) and mutual inductance, .... Does anyone has expierences with questions like this? Maybe you know a suitable software for this problem? Thank you in advance, Timm
