Due to the limitations of the reluctance method, engineers have long sought more accurate ways to calculate magnetic fields. This chapter is devoted to the finiteelement method, the most general and accurate method for calculation of magnetic fields. The finiteelement method can be derived using the basic principle of conservation of energy. The Law of Energy Conservation requires the functional to be zero. Besides the energy functional, the second main requirement of finiteelement analysis is to discretize (break up) the volume analyzed into small pieces called finite elements. The most basic finite element is the triangle. Making a finiteelement model consists of four steps; the four steps are often called preprocessing, because they must be accomplished in order for the matrix equation to be set up and solved for the magnetic vector potential distribution throughout an analyzed device.

Surface ship and submarine magnetic field signatures have been exploited for over 80 years by naval influence mines, and both underwater and airborne surveillance systems. The generating mechanism of the four major shipboard sources of magnetic fields is explained, along with a detailed description of the induced and permanent ferromagnetic signature characteristics. A brief historical summary of magnetic naval mine development during World War II is followed by a discussion of important improvements found in modern weapons, including an explanation of the damage mechanism for noncontact explosions. A strategy for selecting an optimum mine actuation threshold is given. A multi layered defensive strategy against naval mines is outlined, with graphical explanations of the relationships between ship signature reduction and minefield clearing effectiveness. In addition to a brief historical discussion of underwater and airborne submarine surveillance systems and magnetic field sensing pr nciples, mathematical formulations are presented for computing the expected target signal strengths and noise levels for several barrier types. Besides the sensor selfnoise, equations for estimating geomagnetic, ocean surface wave, platform, and vector sensor motion noises will be given along with simple algorithms for their reduction.

Design Considerations of Biomedical Telemetry Devices
The specifications for an implantable medical device (IMD) are provided by the application but share a common set of constraints in size, power, and functionality. This chapter provides a brief overview of the design of biomedical telemetry devices and in particular IMDs using inductive links. The basic system architecture and inductive link fundamentals are discussed, as well as methods and circuits for power transfer and data communication. Safety issues relating to overheating of body tissue as a result of increase of temperature are also examined. There are several methods of harvesting energy for IMDs such as kinetic, thermoelectric, fuel cells, infrared radiation, low frequency magnetic fields, and inductive links. Data communication is called the downlink from the transmitter to the implant, and the uplink from the implant to the transmitter. Due to dual data and power transfer, the carrier amplitude is greater than or equal to the supply voltages.
