Simulation of electromagnetic fields in a microelectrode array

An area of significant potential in Micro-Electro-Mechanical Systems (MEMS)-related technology is the construction of microelectrode arrays that can be used to preferentially kill nearby biological cells while leaving cells more distant from the array intact. This paper details some of the basic considerations related to this research area, and goes on to explore electromagnetic field strength and its spatial variation around a simple simulated microelectrode array near a biological medium with /spl delta/ and /spl epsiv/ characteristics similar to that of human blood. Simulations were conducted at maximum field strengths of |1.1| volts at a frequency of 100 kHz and 1 MHz.
