Coming soonElectromagnetics & Radio Science
EMXploreDiscover then Learn then Experiment
Real engineering and scientific projects, the courses taught alongside them, interactive tools, and portals — in electromagnetics, radio science, and radar engineering.
Projects
Active engineering and scientific projects.
EMXplore is increasingly the home of live research work. Radio Astronomy is active today; the next two projects have their places reserved.
Radio Astronomy
A Saudi radio telescope platform for H I 21-cm observations — telescopes, a data library and archive, data-to-science processing, research tracks, and educational resources.
Open projectRiyadh Space Minaret
Radio astronomy, student projects, live telescope feeds, outreach, and space-science education from Riyadh.
Preview the project pageRadar and Imaging
Electromagnetic simulation, synthetic echo datasets, visualisation, and radar imaging research.

Courses at EMXplore.
Structured course material with equations, visual explanations and interactive tools, delivered as a dedicated learning environment at courses.emxplore.com.
Communication Systems
Signals and systems across the time and frequency domains, modulation, and communication-system analysis.
Open courseSatellite Technologies
Orbital mechanics, satellite geometry, propagation, antennas, communication links, spacecraft, and ground systems.
Open courseMicroprocessors Design
Microprocessor architecture, interfacing, and embedded design, delivered in the courses learning environment.
Open on courses.emxplore.comTools
Interactive engineering tools.
Calculators, simulators and visualisers for working with electromagnetic systems. More are in preparation.
Complex Numbers & Phasors
From algebra and Argand diagrams to phasors and AC circuits, with an interactive visualiser and quiz.
Open toolRF Engineering Lab Toolset
RFSoC resources, SDR experiments, electromagnetic field visualisation, and interactive utilities.
Coming soonPortals
Open portals for the public.
Standalone educational portals developed alongside the research work. They are open engineering resources, not university course material.
Radio Astronomy Lecture
A 52-slide interactive lecture: the 21-cm line, the telescope, calibration, velocities, moment maps and data cubes.
Open lectureHam Radio Portal
Lectures, license preparation, practical resources, and a growing portal for amateur radio — regulations, equipment, operating procedures, and safety.
Open portalSatellite Lecture
A bilingual visual portal on amateur satellite communication — tracking, antennas, Doppler correction, TLE data, LoRa, TinyGS, and student satellite missions.
Open portalThe Approach
Discover → Learn → Experiment
EMXplore connects real questions to learning, learning to experimentation, and experimentation to new discovery: what is built and measured becomes what is explained and taught.
Discover
Start from real questions: natural phenomena, visual explanations, and observations from the field.
Learn
Follow structured lectures and course modules on radio, satellites, radar, antennas, and propagation.
Experiment
Use interactive tools, datasets, simulations, and practical engineering resources, and let the results raise the next question.
