Braided cable modeling

Braided cable modeling

Introduction    The thought of complex electronics often brings up imagery of wires and cables, connecting electrical components on a circuit board to other hardware components. Conventionally, these cables are coaxial (so named due to the central conducting...

Ionosphere behavior

Introduction    When we look up at the night sky, we see through all the layers of our atmosphere into outer space. We see across millions of lightyears to the shining, beckoning pinpoints of light that make us stare up with wonder and curiosity. But what may not be...
Electromagnetic coupling

Electromagnetic coupling

Introduction    A parallel application of electromagnetic (EM) modeling of aircraft is electromagnetic shielding and coupling. My recent post on calculating radar cross-section (RCS) looked at simplifying an airplane CAD model to a more simple canonical geometry, and...

Radar cross-section modeling

Introduction    Normal every day objects can be digitally represented through computer-aided design (CAD) models. Furthermore, these CAD models can be realistically sized, attributed, and imported into optical, mechanical, or radio-frequency (RF) models to help in...
The Fibonacci LFSR

The Fibonacci LFSR

Introduction    Welcome back! From our last conversation about general Linear Feedback Shift Registers, we mentioned there were two flavors of LFSR algorithms: Fibonacci and Galois. Although we ran through a basic implementation of the Fibonacci technique, we can dive...
