The student is asked to acquire experimental time series for voltage and light output on a flickering fluorescent lamp: to develop a mathematical model for the chaotic flicker.
The student is asked to investigate machine dependent rounding processes in various kinds of processor, and applications to processor-dependent encryption. The student is also asked to investigate other processor-dependent computation scenarios.
The student is asked to develop a simple agent-based model for chaotic scattering of balls on a pocketless billiard table.
The student is asked to study the propagation of excitations on an N-wire harness such as might be used in an aircraft, where the transmission line modes have differing propagation velocities.
In this project, a program is written to simulate the dynamics of an electronic double well harmonic oscillator. In particular, conditions for entering a trap in the motion are to be investigated by numerical experiment.
The student is asked to study by literature search, by simulation,
and by measurement, the possibility of making a broadband CP
helical antenna which has variable pitch and diameter. Many
possible profiles for pitch and diameter are possible; the student
should choose one or two of these for investigation.
************************************
This is an experimental project, no simulation at all,
to find out how the resonant frequency and radiation
resistance of a 500mm circular loop antenna is affected
by the presence of a closely-spaced reflecting ground plane.
The antenna is then made into a square shape and differences
noted, for the same wire perimeter. It requires the use
of a network analyser at about 600MHz and the
damped and screened room in the light current lab.
************************************
A literature search of slow wave structures used in antenna design is first made. Examples are constructed and measured. Slow wave structures are typically periodically loaded transmission line or single wire or plates.

This project sets up a diffuse infrared network, mediated by the
USB ports, to connect laptops in an office which may already
be saturated with RF signals usually used for wireless networking.
It can be configured for secure comms between a small
number of selectively equipped machines.
*****************************************
This idea is for short range ultrasonic data communications between close-spaced houses in a street, by bolting transducers onto the incoming rising cold water main. The student investigates the link budget and the practical aspects of this scheme, and determines a specification and constructs a demonstrator.
This project investigates the use of a commercial mobile phone
and link for command and control purposes in a domestic situation.
A demonstrator would be desirable. Typically the phone
downlink can receive TXT information to perform a number
of specific domestic tasks remotely, without affecting the other
traffic on the link.
