A high density capacitor comprises a housing having a cavity, and a plurality of capacitors forming at least one capacitor bank disposed in the housing cavity. The Authentication system is used to store a user’s existing passwords; alternatively, the authentication system creates on demand a transient random pass code that is good for a limited duration. In some embodiments, after emitting the first amount of energy, a method can include denaturing proteins released from cells in the abnormal tissue by emitting a second amount of energy from at least one of the first probe or a second probe inserted into the mammal. A ceramic bonding disk between the metal plate and the RF power feed provides mechanical support for the metal plate and a ceramic body to bond to through the perforations, thus reducing cracking of the metal plate and the surrounding ceramic material. The first and second lower occlusion arms define a lower main body width dimension.
